摘要: 采用平面弹塑性有限元分析方法 ,对藕塘古滑体在三峡水库形成后的稳定性进行了分析。计算中考虑了库水位变化、渗透压力、建筑荷载以及地震等诸多因素对滑体稳定性的影响 ,并给出了滑体失稳的临界破坏条件。为库区移民迁建新址的勘查工作提出了量化的论证。Abstract: The elasto-plastic analyses of the stability of Outang old landslide after construction of Three-Gorges Reservoir are carried out by using 2D FEM. In the computation, the effect of water level variation, seepage flow pressure, construction load, and seismic force on the stability of landslide is considered, and the critical failure conditions of the landslide are given also.
