The Practical Probability Analysis Methods for Stability of Landslide

Abstract:

As an important part of landslide risk assessment, hazard analysis which is based on the probability analysis of landslide stability have caught more and more attentions from researchers and engineers. While in landslide engineering, the uncertainties such as the variability and uncertainty inherent in the geotechnical properties are complex and different, so a single Factor of Safety calculated by traditional deterministic analyses methods can not represent the landslide stability exactly. To provide a more rational mathematical framework to incorporate different types of uncertainties in the landslide stability estimation, some practical probability analysis methods for stability of landslide were proposed, then the user-friendly implementing softwares were recommended. Finally, an application case was described to illustrate the approaches adopted and proved the correctness and feasibility of the proposed methods. The results show the proposed techniques can be applied widely.
