This project focuses on assessing the stability of slopes using advanced techniques and real-world topographic data. The methodology involves the generation of accurate 3D surface models from point cloud data acquired through surveys, employing software like CIVIL3D and Ansys Space Claim for meshing to ensure geometric non linearity. Subsequently, the models are analyzed using the Strength Reduction Method within ABAQUS to simulate the reduction of cohesion and friction angle over time. The stability analysis used gravitational load and can be seismic loads as well. In the next part, the study investigates the effect of installing Glass Fiber Reinforced Polymer (GFRP) piles in slope stabilization, observing a substantial reduction in displacement post-pile installation compared to the initial model, highlighting the significant advantages of such stabilization measures.
Specifically, the recorded displacement post-pile installation measures at 18 cm, marking an impressive 300% decrease compared to the initial displacement of 55 cm without piles installed. These findings highlights the notable advantages of incorporating GFRP piles as key measure in slope stabilization strategies.
