  • Assessing the Effects of Motor Oil, Gypsum, and Sodium Chloride on the Behavior of Lime-improved Grey High Plasticity Clay
    Hamid Gadouri, Brahim Meziani
    Periodica Polytechnica Civil Engineering, 2026
    This study evaluates the effects of motor oil (MO), gypsum (CaSO4·2H2O), and sodium chloride (NaCl) as additives on the geotechnical properties of Grey High Plasticity Clay (GS) improved with 0, 4, and 8% lime (L). Each additive was incorporated into GS at 0, 2, and 4% by dry weight. Unconfined compressive strength (UCS) tests were performed on specimens compacted at their optimum moisture content (OMC) and maximum dry density (MDD) after 7, 30, and 120 days of curing. Results indicated that the plasticity index (PI) of GS decreased with the addition of additives, whether used alone or combined with lime. The introduction of any additive into natural or lime-improved GS enhanced soil classification, with gypsum and NaCl exhibiting a more pronounced effect. Additionally, MDD decreased while OMC increased as lime content rose, due to cation exchange reactions leading to clay particle flocculation. However, MDD increased with higher additive contents, whereas OMC decreased with increasing MO and NaCl but rose with gypsum. UCS values improved significantly with any additive, particularly after 120 days of curing. Microstructural analysis via scanning electron microscopy (SEM) revealed the formation of cementitious compounds and/or ettringite in GS samples improved with lime alone or in combination with gypsum, contributing to strength enhancement.
  • Effect of CaCl2 on the Behavior of Lime-Pozzolana-stabilized Marley Soil
    and Hamid Gadouri
    Jordan Journal of Civil Engineering, 2026
    The geotechnical properties of soils are often influenced by chemical compounds and mineral additives. This study investigates the effects of varying calcium chloride (CaCl2) contents (0% to 6% by weight of dry soil) on the Atterberg limits and classification of Marley soil (MS), stabilized with 8% lime (L), 20% natural pozzolana (NP), and their combination (8%L+20%NP). The research also examines the impact of curing time (1 and 30 days) on the plasticity index (PI) and soil classification, both with and without CaCl2. In the absence of CaCl2, the addition of L, alone or combined with NP, significantly reduced the PI of stabilized MS and markedly improved its classification, particularly with the L-NP combination over longer curing periods. In contrast, NP alone caused only a slight decrease in the PI. The inclusion of CaCl2 further reduced the PI in the MS‒L and MS‒L-NP mixtures. Notably, the transformation in soil classification was more substantial with L and L-NP than with NP alone. A comparative evaluation of the Unified Soil Classification System (USCS) and the British Soil Classification System (BSCS) revealed that the BSCS offered greater precision in classifying stabilized MS, underscoring its suitability for such applications. These findings highlight the significant benefits of incorporating CaCl2, alone or in combination with L or L-NP, in enhancing the PI and the classification of MS. The improvements in both PI and classification are influenced by several factors, including additive type and amount, CaCl₂ content, curing period, and the classification system employed. Keywords: Marley soil (MS), Mineral additives (L and NP), Calcium chloride (CaCl2), Atterberg limits, USCS and BSCS classification systems, Stabilization.
  • Flood Risk Assessment in Khemis Miliana, Algeria: An Integrated Modeling Approach
    Brahim Meziani, Hamid Gadouri
    Advances in Transdisciplinary Engineering, 2025
    This study develops an integrated hydrological and hydraulic model for the Oued Souffay watershed, located in the region of Khemis Miliana, Algeria. The primary objective is to assess flood risks and propose effective mitigation strategies for this vulnerable area. The methodology combines geospatial analysis in ArcGIS with specialized modeling software: HEC-HMS (Hydrologic Modeling System) for simulating rainfall-runoff processes and HEC-RAS (River Analysis System) for one-dimensional steady-flow water surface profile computations. Key steps included watershed delineation and morphometric analysis using a Digital Elevation Model (DEM), preparation of geometric data for the river channel (including centerlines, banks, flow paths, and cross-sections) using the HEC-GeoRAS extension, and subsequent import and refinement of this data within HEC-RAS. Manning’s roughness coefficients were carefully assigned based on land cover. The simulation shows how flood areas can be overlaid for a certain weather event. It helps find the places in Khemis Miliana that are at high risk. The study says using HEC-HMS, HEC-RAS, and ArcGIS together is a good way to manage flood zones. It also points out that flooding can hurt infrastructure. So, we need things like better drainage, soil reinforcement, and retention basins to make the city stronger against floods.
  • Assessing the Slope Stability Risk Using LEM: Case Study of the Kouala Landslide in Medea Region, Algeria
    Hamid Gadouri, Brahim Meziani, Ilyes Selami
    Advances in Transdisciplinary Engineering, 2025
    This research examines slope instability at the Kouala site in Medea (northern Algeria), where clear signs of ground movement have already been observed. To quantify the degree of risk, the Limit Equilibrium Method (LEM) was applied, integrating both geotechnical and hydrological parameters such as cohesion, internal friction angle, plasticity index, unit weight, rainfall infiltration, and groundwater level. The simulations reveal that prolonged or intense rainfall reduces the shear strength of marl formations and lowers the factor of safety below the acceptable threshold. The most critical sector is the upper slope, where values fall under 1.0 in saturated conditions, indicating a high probability of rotational sliding. Although the deeper layers are comparatively more resistant, they remain vulnerable to infiltration over time. Thematic maps of cohesion, friction angle, and slope gradient emphasize strong spatial contrasts, with almost 70% of the slope classified as highly to very highly susceptible. These findings confirm the urgent need for stabilization strategies, including drainage control and soil treatment techniques, particularly chemical stabilization with and without reinforcement.
  • Geotechnical and geophysical assessment of the 2011 Daly Brahim landslide, in the southwest of Algiers, Algeria
    Brahim Meziani, Mira Filali, Gadouri Hamid
    Proceedings of SPIE the International Society for Optical Engineering, 2024
    Landslides are a prevalent phenomenon in the vicinity of Dely Brahim city in the Southwest of Algiers. The majority of these landslides remain active to this day, frequently occurring in the Pliocene marl formations, particularly those outcropping in the Sahel zone (coast in Arabic). These landslides result in damage to neighboring properties or public infrastructure, causing social and economic disruption or environmental degradation in most urban and coastal areas of the country. The principal objective of this study was to enhance our comprehension of the initiating processes and mechanisms of these landslides. Initially, Electrical Resistivity Tomography (ERT) was employed to monitor the behavior of electrical resistivity within the landslide area. The resulting models were then cross-checked with geotechnical data from in situ and laboratory tests. The combined interpretation of the data revealed that a potential sliding surface could be associated with a low resistivity horizon within the shallow layers of marls at a depth of approximately 9 metres. Consequently, the results indicated that the upper marl formations were generally weathered and characterized by higher water content than the deeper formations. Additionally, factors such as demographic growth and increased urbanization have contributed to the occurrence of landslides in the region.
  • Polypropylene fiber’s effect on CBR in lime-stabilized sulfate-contaminated expansive clay

  • Landslide Geohazard Assessment Using the Finite Element Method: A Case Study of PK-21 Along the Djendel Highway Corridor, Algeria
    Mira Filali, Lisa Muggary, Hamid Gadouri
    Proceedings of SPIE the International Society for Optical Engineering, 2024
    The stability of natural and engineered slopes is significantly influenced by cutting and filling activities during road construction, which can lead to potential landslides. This study focuses on conducting a slope stability analysis using geotechnical data obtained from investigations and landslide analyses carried out at Km-21 of the Fourth Ring Road in Djendel, Algeria. The research examines the effects of excavating a section of residual clay, which triggered a landslide. To understand the underlying processes of this landslide, the physico-mechanical characteristics of the soils obtained from boreholes were analyzed. Laboratory test results, including grain size distribution, Atterberg limits, water content, shear strength, and compressibility, were meticulously examined. The findings revealed that the soils were fine-grained and heterogeneous, with moderate to high plasticity. It was observed that the upper soil layer (residual clay) exhibited lower shear strength parameters, with cohesion at 5 kPa and a friction angle of 23°, compared to the undisturbed formations beneath it, which had cohesion of 15 kPa and a friction angle of 25°. The stability analysis was performed using PLAXIS 2D, a software based on Finite Element Methods (FEM). The results indicated a significant impact of the excavation on slope stability. The factor of safety was 1.383 before excavation in dry conditions and dropped to 0.951, indicating that the upper layer is prone to instability after a portion of its total weight is excavated. This decrease in the factor of safety demonstrates the critical role of proper slope management and soil characterization in preventing landslides during construction activities.
  • Elaboration and validation of IP-ANN model of fly ash-clayey soils
    Yasmina Kellouche, Hamid Gadouri, Ahmed Bilal Sari, Mohamed Nour Soulaymane, Alvaro Vumi
    Proceedings of SPIE the International Society for Optical Engineering, 2024
    This study aims to develop an Artificial Neural Network (ANN) model to predict the Plasticity Index (PI) of clay soils stabilized with fly ash. A total of 193 datasets were collected from previous studies, normalized, and used for training, testing, and validating the model using the backpropagation algorithm. The results indicated that the PI-ANN model achieved high accuracy, with a correlation coefficient exceeding 99% and minimal Mean Square Error (MSE). Sensitivity analysis showed consistency with existing literature. Validation using experimental results from three independent studies confirmed the model’s performance, achieving a regression coefficient of 99% and a mean relative error of 0.92%. Additionally, the PI-ANN model outperformed a comparable statistical model, demonstrating its reliability for predicting the PI of high-plasticity clay soils.
  • Analyzing Landslides Through Geotechnical and Geophysical Surveys: A Case Study the Landslide of the Toll Station in the Djebahia Region of Bouira, Algeria
    Brahim Meziani, Hamid Gadouri
    Advances in Transdisciplinary Engineering, 2023
    This paper focuses on assessing natural hazards in northern Algeria, particularly landslides, earthquakes, and floods, which result in substantial material and human losses. The specific objective of this study is to investigate landslides in the Djebahia region, specifically related to the water transfer pipeline from the Acerdoune dam to M’sila town. The research collects and analyzes geophysical and geotechnical data to identify the key factors influencing landslides in this area.The study reveals that the main factors contributing to induced landslides in Djebahia are the steepness of the terrain, water availability, and soil composition, particularly marl and clay. These factors can lead to varying depths of the sliding surface, ranging from 7 to 20 meters. To mitigate the risk of movement in this region, the paper suggests the installation of two series of piles. Additionally, inclinometers have been placed near these piles to monitor depth-related movements. Over a two-year period, the inclinometric results indicate acceptable displacements at various depths.
