Analysis of Weakening Law and Stability of Sliding Zone Soil in Thrust-Load-Induced Accumulation Landslides Triggered by Rainfall Infiltration

This study investigated the weakening model, law of mechanics parameters, and stability sliding zone soil associated with thrust-load-induced accumulation landslides triggered by rainfall infiltration. The spatial morphological characteristics rule sapping process were analyzed, considering constitutive equation soil, in order to establish a state curve for coefficient based on “S”-shaped curve. Moreover, formula calculating slope this failure mode was derived applied calculate deformation body Danbo reservoir, China. results show that type landslide exhibits steep upward slow downward trends, affected infiltration, its develops gradually from trailing edge front edge. In equation, mechanical parameters is manifested as shear stiffness, while reflects process. main factors affecting accuracy calculation are values model assessment development stage zone.
