STUDY ON DYNAMIC DEFORMATION MECHANISM OF LANDSLIDE IN DRAWDOWN OF RESERVOIR WATER LEVELTAKE BAISHUIHE LANDSLIDE IN THREE GORGES RESERVOIR AREA FOR EXAMPLE

  • 摘要: 在每年的库水位下降期间,三峡库区的许多滑坡都出现了较大变形。为了深入研究库水下降作用下滑坡的动态变形机理,评价和预测此类滑坡的稳定性及发展趋势,本文以白水河滑坡为例,在现场地质调查和详细地质勘查的基础上,充分利用十多年监测数据,分析其变形特征、失稳机理、影响因素及稳定性,预测了其变形发展趋势。研究结果表明在水库水位下降的过程中,由于滑坡岩土体渗透性能较差,地下水来不及及时排出,滞后于水库水位的下降,滑坡受到了坡体内地下水向外的渗透动水压力作用,从而使得滑坡稳定性降低。另外库水位下降速度越快,滑坡的位移速率也越大,表现出阶跃型动态变形特征。
