Influence of Soil Fabric and Gradation on Excess Pore Water Pressure Development Based on Laboratory PWP Tester
Božana Baćić, Ivo Herle
Geotechnical and Geological Engineering, 2026
The build-up of the excess pore water pressure (PWP) during shearing under constant total stresses can significantly influence the stability and performance of geotechnical structures, particularly in coarse grained soils under cyclic and dynamic loading conditions. This study investigates the role of soil fabric and granulometric properties in the generation of the excess PWP using a newly developed PWP Tester. Series of experiments were conducted on both natural and crushed sands with varying grain size distributions, grain shapes, and particle orientations. The results indicate that the resistance to the excess PWP build-up in natural soils increases with larger mean grain diameter and a reduced amount of fines, while crushed sand with narrower grain size distribution show a slight increase in resistance to the excess PWP development. Furthermore, the findings suggest that soil resistance to the excess PWP cannot be adequately captured by solely considering the relative density, and that the soil fabric plays an equally significant role. This study contributes to a deeper understanding of the soil behaviour under cyclic loading in undrained conditions, offering a simple and straightforward method for testing the soil tendency to the excess PWP evolution.
Incorporation of a hypoplastic material model for sandy soils into a dynamic ALE formulation suitable for structures subjected to moving loads
Atul Anantheswar, Sebastian Ullmann, Ines Wollny, Sebastian Skatulla, Ivo Herle, Michael Kaliske
Transportation Geotechnics, 2026
Recent research has shown that an Arbitrary Lagrangian Eulerian (ALE) formulation can be leveraged to improve the efficiency of simulating structures subjected to moving loads, such as pavements. However, when modeling pavements, subsoil characteristics are not given much importance recently, and the subsoil is often modeled by simple linear elasticity. In this work, a hypoplastic material model capable of accurately describing the behavior of cohesionless soils, is used to model the subsoil response. Additionally, the calibration of the hypoplastic model to obtain material parameters is described. Further, the logarithmic strain approach to extend this model to finite deformations is detailed, and the incorporation of this material model into a dynamic ALE formulation is explained. Finally, the results of a transient simulation of the pavement response, when subjected to a moving load, are provided.

Structure and Infrastructure Engineering, 2026
The Digital Twin Road initiative aims to improve road infrastructure monitoring and maintenance through real-time data integration, computational modeling, and predictive analytics. However, the reliability of such digital twins is significantly affected by uncertainties in both material properties and sensor data. This paper provides a comprehensive evaluation of uncertainty sources within the CRC/TRR 339 – Digital Twin Road project. Material-related uncertainties stem from the intrinsic variability of asphalt, concrete, and soil due to production methods, environmental exposure, and construction practices. These include aleatoric uncertainties from natural variability and epistemic uncertainties from knowledge gaps. Sensor-related uncertainties arise from limitations in sensor technology, calibration, environmental influences, and data processing algorithms. Detailed case studies, including weigh-in-motion systems, drone-mounted laser scanning, and smart materials such as mineral-impregnated carbon-fiber (MCF) reinforced low-clinker concrete, illustrate how uncertainties accumulate and propagate across the Digital Twin Road framework. The classification of uncertainty into aleatoric and epistemic categories is discussed. Understanding these uncertainty sources is essential for improving the predictive accuracy and ensuring a robust representation of real-world road systems.
Experimental studies on the cyclic behaviour of reinforced unbound railway base courses
Claudia Bräunig, Ivo Herle, Ulrike Weisemann
E3s Web of Conferences, 2025
In railway construction, base courses of unbound coarse-grained material are usually placed between the existing subgrade and the track. Geosynthetics, in particular geogrids, are used to improve the system behaviour. The reduction in the thickness of the base course due to the geogrid is based on empirical approaches. In this work triaxial tests were performed to investigate the influence of the geogrid. A specimen size of d · h = 100 · 200 mm was chosen. This small sample size saved material, reduced workload and allowed the use of a standard triaxial apparatus. However, the base course material and the geogrid had to be geometrically scaled. Cyclic triaxial tests were carried out on the unreinforced and reinforced specimens with the aim to reproduce the conditions caused by rail traffic loading. For this purpose, the low stress and high number of loading cycles N = 500,000 were chosen. It was shown that the inserted geogrid reduces the magnitude of deformation and the accumulated strains compared to the unreinforced material.
Triaxial Compression of Sand-Fines Mixtures at Low Confining Pressures
Sebastian Ullmann, Selma Schmidt, Ivo Herle
Geotechnical and Geological Engineering, 2025
A series of triaxial compression tests was performed on a natural sand-fines mixture under both drained and undrained conditions at initial confining pressures ranging from 20 to 300 kPa. The tests aimed to better understand the mechanical behaviour of the soil at low stress levels. Additionally, images of the soil fabric were taken using a µCT device, revealing that the fabric was characterised by the sand grains being fully embedded within the fine-grained matrix and that only few direct contacts between the sand grains existed. The results of the triaxial tests showed that the fabric of the sand-fines mixture significantly influenced the macroscopic properties of the specimens when compared to clean sands. In the drained triaxial tests, the dilatancy and friction angles showed minimal dependence on the confining pressure, even at pressures below 60 kPa. The undrained triaxial tests showed different response patterns in the development of excess pore water pressure. Tests starting from lower confining pressures resulted in a greater build-up of pore water pressure after reaching the phase transition line, whereas at higher confining pressures the soil exhibited lower excess pore water pressures.
Soil fabric of coarse-grained soils sedimented under water and its relation to relative density and excess pore water pressure
Božana Baćić, Ivo Herle, Martin Oppermann
Granular Matter, 2025
The soil fabric varies significantly depending on the deposition process that forms the grain skeleton. Each deposition method produces a specific type of soil fabric, which can be linked to a particular soil density. When represented as relative density, determined using limit densities from standard index tests, a wide range of relative densities can be observed for different sands produced by the same deposition method. The influence of this variation in relative density, resulting from a single deposition method, on the development of the excess pore water pressure (PWP) should be further investigated. A fast testing of the excess PWP accumulation in sandy soils during undrained cyclic shearing can be easily performed using the newly developed PWP Tester. In the PWP Tester, specimens are prepared through sedimentation in water, which yields a comparable fabric in different sands but significantly different relative densities. Despite these relative density differences, the rate of the excess PWP evolution during undrained shearing is remarkably similar among different sands. This indicates that relative density should not be regarded as a primary factor influencing the development of the excess PWP and that the soil fabric plays equal or even a greater role.
Scaling effects under monotonic shear loading on unbound reinforced base courses
Claudia Bräunig, Ivo Herle, Tom Schulze, Ulrike Weisemann
Geotechnik, 2025
Durch den Einsatz von Geogittern in ungebundenen Tragschichten können die Tragfähigkeits‐ und Gebrauchstauglichkeitseigenschaften verbessert werden. Um die Tragwirkung dieses Verbundsystems zu analysieren, wurden Triaxial‐ und Rahmenscherversuche durchgeführt, in welchen die Auswirkung der Skalierung der Versuchsmaterialien Tragschichtmaterial und Geogitter unter monotoner Scherbeanspruchung untersucht wurde. Bei der Untersuchung des Systems Tragschicht – Geogitter mittels bodenmechanischer Versuche werden aufgrund der begrenzten Probenabmessungen häufig kleinere Öffnungsweiten des Geogitters und kleinere Korngrößen des Tragschichtmaterials gegenüber denen in der Baupraxis verwendet. Bei der Übertragung der Ergebnisse sind Skalierungseffekte zu beachten, welche in der vorliegenden Arbeit untersucht werden. In den Triaxialversuchen wurde das Verhältnis der Öffnungsweite des Geogitters zur Korngröße beibehalten, es wurden zwei Tragschichtmaterialien untersucht. In beiden Skalierungen führte der Einsatz von Geogittern im Tragschichtmaterial zu einer Verbesserung der Tragfähigkeit durch eine Erhöhung der maximal aufnehmbaren Spannung. In den Rahmenscherversuchen wurde das Verhältnis zwischen Öffnungsweite des Geogitters und Korngröße verändert. Die Versuche mit bewehrten Proben führten bei parallel zur Scherrichtung gewählter Anordnung des Geogitters im Scherspalt zu geringeren aufnehmbaren Scherspannungen.
Heterogeneous and scale-dependent behaviour of an initially dense sand specimen in triaxial compression
Selma Schmidt, Ivo Herle
Granular Matter, 2025
The heterogeneity of a dense sand specimen in triaxial compression has been revealed in many different studies using tools such as x-ray computed tomography. It has been shown that a significant variation of the soil variables already exists at the initial state and that, if shear banding occurs, all variables localise inside the specimen. To resolve the discrepancy between such observations and the assumption of a homogeneous specimen, which is commonly made in the interpretation of triaxial tests, one could either extract the local soil behaviour rather than the global one or use the initial distribution of the variables as the initial state of a boundary value problem. For both purposes, the size of a representative elementary volume (REV) is determined regarding the void ratio, two contact fabric descriptors, the volumetric and deviatoric strain. The size of the REV is either determined for individual loading states or by considering the evolution of deforming elements throughout the triaxial test. At the final loading state, a REV size of 3.6 $$d_{50}$$ is identified, which is also the size where the statistical distribution of the variables becomes independent of the element size. The same size is determined for the deforming elements and is therefore used to extract the soil behaviour from the evolving shear band. The local soil behaviour is found to be much simpler than the global one, which suggests that the complexity of the global behaviour mainly results from homogenising the highly different zones inside the specimen. Graphical Abstract Extraction of the soil behaviour inside the evolving shear band with the help of deforming representativeelementary volumes. The volumetric behaviour is represented by the evolution of the void ratio and the evolution ofthe contact fabric anisotropy is closely connected to the stress-strain behaviour. The soil behaviour on the REVscale might form the basis for an alternative approach for the development and calibration of constitutive modelsconsidering the heterogeneity of a soil specimen.
EVOLUTION OF FABRIC AND STRAIN WITHIN REPRESENTATIVE ELEMENTARY VOLUMES INSIDE A SHEAR BAND BY TRACKING GRAINS OF A SAND SPECIMEN IN TRIAXIAL COMPRESSION
S. Schmidt, I. Herle
Iop Conference Series Earth and Environmental Science, 2025
It has been shown in several different studies that the behaviour of sands in triaxial tests is, in contrast to common assumptions, not homogeneous and that, after the localisation of strain, most of the soil behaviour takes place inside the shear band. In this work, the evolution of fabric and strain is extracted from the evolving shear band with the help of representative elementary volumes (REV) and compared with other regions inside the specimen as well as the overall behaviour. The size of the REV is determined by analysing the evolution of the fabric variables and the strain inside cubic elements with increasing size. For this purpose, a set of grains is assigned to the elements at the initial state and the grains are tracked throughout the test. The REV is then placed in different regions of the specimen and the evolution inside and outside the shear band as well as the global behaviour is compared.
INFLUENCE OF SAND FABRIC ON PORE WATER PRESSURE BUILD-UP
B. Baćić, I. Herle
Iop Conference Series Earth and Environmental Science, 2025
The sand fabric is created depending on the art of the grain deposition. A certain deposition method creates a specific type of soil fabric that can be linked to a particular soil density which, when related to the limit density states obtained from the standard index tests, can vary within a large range for different sands prepared by the same method. This paper aims to clarify the impact of varying the relative density in the case of one deposition method on the pore water pressure (PWP) accumulation in sands. A simplified cyclic shear test (PWP Tester) enabling a fast testing of the PWP accumulation during undrained cyclic shearing in granular soils is used for this purpose. The tested specimens are pluviated under water via a funnel and thus have a similar fabric. The results show a greatly comparable rate of PWP accumulation during undrained shearing, despite the fact that the relative densities following the same soil deposition vary greatly for different soils.
