One‐way coupled seepage‐stress slope stability analysis using ABAQUS

Abstract Seepage is a significant contributor to slope failure. This study investigates the stability of homogenous soil slopes under steady seepage using a one‐way coupled seepage‐stress analysis in ABAQUS, with results validated against those from Slide2. Quantitative simulations across various scenarios show that both methods yield good agreement in terms of Factor of Safety (FOS) and failure surfaces, though Slide2 is found to be slightly more conservative. Additionally, a sensitivity analysis on soil parameters, specifically cohesive strength and friction angle, reveals their considerable impact on FOS and failure surface development. This study suggests that one‐way coupling provides a practical balance between computational efficiency and accuracy for slopes under steady seepage, making it suitable for routine engineering with simple hydro‐mechanical conditions.
