Abstract

Abstract

Based on detailed filed survey and deformation monitoring data for many years, deformation characteristics and formation mechanism of Xieliupo landslide in Zhouqu has been discussed. The result reveal that the landslide which lies in Pingding-Huama Fault Zone belong to a typical giant fault zone landslide being in an unstable state all the time.Xieliupo landslide is formed under the coupling of endogenic and exogenic geological processes.Shattered fault zone is a sufficient condition which resulted in Xieliupo landslide and fault activities lead the slope to plastic flow deformation.Rainfall is a main factor which triggering large-scale slip of the landslide.Furthermore, earthquake, toe cutting and other factors play promoting roles in the landslide's development and evolution.Therefore, further studies on the formation mechanism and disaster pattern of fault zone landslide have important significance towards the prediction and prevention of this type of landslide.
