Abstract

Colluvial landslides were frequently triggered by rainstorms. Their mechanisms are studied in this paper through seepage simulation and slope stability analysis. The results show that loose colluvial soil deposits with gravel contents above 50% by weight should be highly concerned during rainfall. The originally unsaturated soils in these deposits may be saturated very quickly during rainfall, which induces a considerable decrease of factor of safety. Slopes composed of such soils show a lower safety margin compared with slopes composed of soils with gravel contents smaller than 50%.
