吾隘中学滑坡稳定性数值模拟分析

结合滑坡现场勘察和物理力学试验,运用FLAC3D软件,对吾隘中学不同水文地质条件下的滑坡进行模拟,得出其安全系数、位移以及剪应变增量分布。结果表明:滑坡在饱和状态下,剪应变增量集中区贯穿于覆盖层与基岩交界处,最大位移分布在覆盖层,滑坡处于不稳定状态。

Numerical Analysis on Stability of Landslide in Wuai Middle School

On the basis of site investigation on landslide and the physical and mechanical experiments,Wuai Middle School Landslide in various hydrogeological conditions was simulated by FLAC3D so as to get its safety factor,displacement and distribution of shear strain increment.The result shows that the landslide,under the saturation state,has the shear strain increment zones go through the interface of overburden and base rock,and the maximal displacement is distributed in the overburden,thus the landslide is in unstable state.
