| 摘 要： | 三峡水库正常蓄水后,库水位在175-145m之间周期性波动,库岸斜坡地下水渗流状态将会发生较大的改变.可能导致斜坡失稳.本文采用数值模拟方法,以巴东县西壤坡为例,分析了在库水位升降与降雨联合作用下斜坡体内地下水渗流场的变化过程,通过渗流场与应力场的耦合模拟分析,探讨了库岸斜坡在水位变化及降雨作用下稳定性的变化特征.

| Abstract: | When the water level of Three Georges Reservoir fluctuates periodically from 175m to 145m,the seepage situation of slope underground water will change a lot,which probably leads to slope failure.Taking Xirang slope as an example,this paper analyzes the slope change process under the combined action of water level alternation and rainfall via numerical simulation,and studies the characteristics of slope consistency under circumstances of water level alternation and rainfall through hydrological and mechanica... |
