Stability Evaluation of the Deposit Body under Water Level Variation Based on FLAC 3D
摘要
Abstract
Water level variation in reservoirs is one of the most important factors that can cause landslide. The deposit body in western China is taken as study object. Via FLAC3D soft,the stabilities of this deposit body are calculated in river level condition, normal storage water level condition and water level drawdown condition. The influence on deposit body caused by water level variation is analyzed by the comparison of plastic zone, maximum displacement and safety factor of three working conditions. It can be concluded from the analysis that the safety factor decrease obviously in water level drawdown condition but only part of the deposit body is affected.关键词
