| 摘 要： | 三峡水库建成后,库水位将在145～175m之间发生变动.库水位的骤然升降引起的滑坡体内孔隙水压力的突然变化也必将对滑坡的稳定性产生显著的影响.以万州区安乐寺古滑坡前缘松散堆积体为例,利用有限差分软件FLAC3D对滑坡渗流场变化特征进行了数值模拟分析,同时在滑坡渗流场模拟的基础上,采用强度折减法对滑坡的稳定性进行了计算,...

| Abstract: | The water level will fluctuate between 145 m and 175 m after the completion of Three Gorges Reservoir.The pore water pressure changes in landslide due to the water level rising and descending will have significant impact on the landslide stability.With the soil deposits at the top of Anlesi landslide in Wanzhou as an example,the landslide seepage numerical analysis is conducted by the FLAC3D software.Based on the landslide seepage numerical simulation,the stability of the landslide is calculated with the st... |
