Synopsis

Slopes are designed in infrastructure projects to ensure the safety and stability of inclined surfaces. Factors influencing slope stability include inclination, height, material properties, drainage systems, and environmental conditions. Reinforcement techniques such as retaining walls, concrete and rock fills, and anchoring systems are employed to enhance slope stability. Additionally, analyzing the effects of dynamic stresses caused by seismic activity is crucial, especially in earthquake-prone regions. Seismic slope stability analyses classify the effects of dynamic stresses into two main categories: inertial instability and weakening instability. Inertial instability occurs when dynamic stresses temporarily exceed soil strength, causing permanent deformations. Weakening instability, on the other hand, results in significant reductions in shear strength under dynamic loading, potentially leading to soil liquefaction or other stability issues. Assessing liquefaction potential and identifying critical slip surfaces are essential for maintaining slope stability. This study addresses techniques used in seismic slope stability analyses. Detailed examinations are provided for methods such as pseudo-static analysis, Newmark analysis, and approaches focusing on inertial and weakening instability.
