摘要
三峡库区是一个滑坡多发区,滑坡的发生危及人民生命和财产安全.通过介绍三峡库区某滑坡的工程地质概况,分析该滑坡的成因机制和监测变形特征.运用Geo-Slope软件,考虑该滑坡的实际受力和三峡水库库水位的变动,对不同工况下的滑坡进行稳定性分析和评价.研究表明,该滑坡在工况2条件下处于潜在不稳定状态,其他工况处于基本稳定状态.滑坡有可能发生整体失稳,应采取相应的防护措施.
Three Gorges Reservoir is a landslide-prone area.The occurrence of landslides endangers people′s life and property safety.By introducing the engineering geology overview of a landslide in Three Gorges Res-ervoir are genetic mechanism and monitoring deformation characteristics of the landslide is analysised.consid-ering the actual forces and the mutative water level in the Three Gorges Reservoir,for different conditions its stability is analyzed and evaluated by Geo-Slope software.Studies have shown that the landslide in the second working condition is potential unstabe state;the others are basically in stable state.
