This study investigated the deformation characteristics and mechanisms of Baiyansizu landslide under coupled effects crack development, rainfall infiltration, road loading. Numerical simulations were performed using GeoStudio software (Version 2018; Seequent, 2018) to analyze geological factors external disturbances affecting seepage dynamics. Four additional landslides (Tanjiawan, Bazimen, Tudiling, Chengnan) selected as comparative cases investigate differences in across these cases. The results demonstrate that rear-edge was predominantly governed by patterns, with effective exhibiting a dual regulatory mechanism: long-term reduced shear strength through sustained infiltration-induced progressive creep, whereas short-term rainstorms generated step-like via transient pore water pressure amplification. further revealed multi-physics coupling nonlinear stability evolution controls. These findings highlight fissures substantially amplify infiltration efficiency, thereby establishing features predominant determinant. Road loading observed accelerate shallow deformation, coefficient threshold values triggering accelerated creep phases when thresholds exceeded. Through analysis five typical cases, it demonstrated interactions between resulted distinct mechanisms. Variations thickness, evolution, magnitudes, identified critical influencing patterns. research provides significant empirical insights theoretical frameworks for monitoring early warning system development.
