藕塘古滑体在三峡水库形成后的稳定性分析

The Analysis on the Stablity of the Outang Old Landslide After the Three Gorges Reservoir is Finished

采用极限平衡和三维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计算分析。计算中考虑了水库水位变化、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察工作提供了量化的论证。

For the stablity assessment of the Outang old landslide after the construction of the Three Gorges reservoir completed, calculation and analysis have been conducted with limit equilibrium method and 3-D elasto-plastic FEM in consideration of influences of water level change, seepage flow pressure, constructional load and seismogenic force. The conditions of the landslide revivification have been given.
