Based on the geological exploration of Nanzhu landslide,the stability analysis of the landslide is studied when the water level of the Yangtze River falls from 175 m to 125 m.

According to the characteristics,material structure features,and the geological natures of the landslide, the calculation and evaluation for the stability of the landslide are performed with the consideration of three kinds of loading situations and residual thrust method.

The Zuoyituo landslide 83 km from the Three Gorges dam,is one of the major prospecting landslides in the reservoir area of the Three Gorges,lying on the southern bank of the Changjiang River, in the Nanmuyuan Village of Badong County of Hubei Province.

Simulation of rockfall at Mingshan in Fengdu by discrete element method;

This paper introduced engineering geologic conditions of Baishapo rockfall in the Three Gorge reservoir area,analysed its formation mechanism and calculated its stability under main load compo.

Based on the analysis of the physical components,characteristics of the weak layer,the interface between the riverside slumping mass and bedrock and the characteristics of hydrogeology,combined with the numerical simulation and stability calculation,the variation of stability of the riverside slumping mass after the rising of the water level in the Three Gorges reservoir area is studied.

The data of shear strength experiments of the landslide slip layer used in different methods in Huangtupo landslide riverside slumping mass are analyzed.
