Abstract
Rainfall-induced slope failure is a major geotechnical disaster and has been frequently reported in many regions worldwide. This work aimed to study the rainfall (climate) influence on slope stability. The climate is represented by precipitations rate, precipitation duration and the stability of this unsaturated slope in natural terrain was evaluated based on a key indicator which is “safety factor”. The finite elements software (PLAXIS2D) was used to analyze the stability of the slope. The factors of safety were evaluated by means of fully coupled flow-deformation analyses and then compared with the various controlling factors: rainfall intensity, rainfall duration, angles and heights of slopes, soil characteristics and hydraulic conductivity of the soil. The results were discussed in this paper and led to confirm the relationship existing between landslide and climate effects considered in this analysis. In fact, this relation is observed for most part of the north Algerian instabilities.
