Monitoring and analysis of deep-lying displacement of Huanglashi landslide;

This paper briefly memorized prevention and cure course of Lianzi Cliff dangerous rock body and Huanglashi landslide in Sanxia Gorges of Changjiang River.

Action law of groundwater and evaluation of Huanglashi slope stability;

The calculating method of seepage is adopted in which the groundwater level approaches to the real situation;and the head of groundwater and the seepage pressure are calculated when the groundwater level changes in the seepage flow field of the Huanglashi slope.

A displacement dynamics parameter of debris landslide induced by water and its application t o stability evaluation——Taking Huanglashi landslide in Three Gorges Reservoir area for example;

In order to discover a new approach to the quantitative analysis of the evolution and stability of the complex landslide trace pattern, the fractal theory is employed to analyze the geometrical fractal pattern of the self_similar boundary trace between the Huanglashi landslide and the Huangtupo landslide in the fore_reservoir region of the Three Gorges, Changjiang River.

Based on the disaster of the Three Gorges Huanglashi landslide, the author calculated the sliding speed of the landslide and its maximum surge, also analyzed its effect on the important towns and buildings located at the upstream and downstream.
