摘要
位于清江岸边的古树包滑坡曾使水布垭面板堆石坝工程对外交通一度中断。依据古树包滑坡体的地质背景与工程地质特征,在对其成灾原因进行研究的基础上,应用非线性有限元方法对降雨条件下古树包滑坡体的稳定性进行了研究。探讨了降雨在坡体中形成的暂态饱和区对滑坡体稳定性的影响,研究了该滑坡体再次启动的条件,并对其加固措施提出了建议,为该滑坡体的防治工程提供了重要参考。
The Gushubao landslide had ever blocked the traffic of the Shuibuya water control project site. Based on the geological background and the site engineering geological characteristics of the Gushubao landslide of Qingjiang River, the nonlinear finite element method is applied to study the stability of the slope during rainfall. The sensibility of influence of the underground water and the rainfall on landslide stability is analyzed. The influence of transient saturated zone in the slope due to rainfall to the stability on the slope is discussed. The conditions of reliding of the Gushubao landslide are discussed. The basis of prevention and control works of the landslide is provided.
