Numerical analysis on landslide mechanism of a talc sheet rock slope at Liangjiaren hydropower station
摘要
Abstract
Landslide disaster is one of the most frequently happening geological disasters ,the process of which is governed by ter‐rain geometry ,characteristic of landslide rock mass ,characteristic of slip surface and external environment loads such as earth‐quake ,rainstorm and human activity .Based on the fact of landslide disaster at bedding rock slope of left bank of Tiger‐leap‐Gor‐ger at Liangjiaren hydropower station ,on October 28 ,1996 ,a landslide model was built up to fit the slide rock mass ,slip face ,as well as the effect of earthquake and rainstorm according to a large number of geological surveys .Then a series of numerical sim‐ulation of landslide was proposed to study the influencing rules of slip friction coefficient and strength of slide rock mass on the landslide geometry ,debris size and velocity of landslide ,so the process of landslide of bedding rock slope was feedback analyzed and the slope stability was discussed .This method could be used in following stability research of similar slopes and correspond‐ing assessment of geological hazards .关键词
