摘要
在对西南某水电站库区一多期次巨型滑坡的工程环境条件、物质组成、自身结构及变形破坏特征等方面认真调查和研究的基础上,选择代表性剖面,分5种不同组合,利用SlopeCAD和VV2001两种计算分析程序,对滑坡整体及分期次稳定性进行了定量分析。在此基础上,采用能量法、潘家铮法、以及美国土木工程学会建议的方法,对局部失稳滑坡体可能产生的滑动速度及引起的涌浪高度进行了定量预测和分析,并据此对其可能给大坝及人民生命财产安全等多个方面带来的危害程度进行了评价。
The authors investigate and research into the engineering environmental conditions and the (characteristics) of material component, self-structure, deformation and destruction of some multiple and (large) landslide in reservoir area of some southwest hydropower station in China in this paper. By choosing the representative profiles and five kinds of combined work conditions and using two calculation and (analysis) programs (SlopeCAD and VV2001), they evaluate synthetically and analyze quantitatively the (integral) and time stability. At the same time, using the methods of energy, PAN Ja-zheng, and the method advised by ASCE(The American Society of Civil Engineers), this paper also synthetically (evaluates) the potential hazard extent of the landslide to the dam and the people's life and property safety, etc. through forecasting and analyzing the possible sliding speed of local failure landslide and the height of surging wave caused by it.
