FLAC法在三峡库区滑坡稳定性分析中的应用

The Application Study of Stability Analysis of Landslide About The FLAC Method In The Three Gorges Reservoir Area

本文采用传递系数法和基于的强度折减FIAC法,对库区某滑坡在库水位变动工况下的稳定性进行了对比分析计算。结果表明,两种方法计算结论基本一致,但FIAC法能反映出滑坡体内的应力和应变变化规律。对工程治理实际具有更强指导意义。

In this paper, attention is payed to comparison of transfer cofficient methods and strength reduction methods of FLAC （Fast Lagrangian Analysis of Continue）.For instance ,a typical landslide in the Three Gorges reservoir area is analyzed.The calculation results shows some consistency and indicates that FLAC can reflect the law of changes of stress and strain in landslid,which makes it superior to transfer coefficient methods.
