摘要
所研究的堆积体位于澜沧江中游某水电工程坝前近坝部位,该堆积体一旦失稳将直接影响到大坝的安全。为了正确评价堆积体的稳定性和制定有关工程处理措施,选取堆积体四条主要的剖面建立计算模型,对四条剖面进行了最危险滑面搜索,确定了最可能发生滑动的局部滑体的范围和位置,并对其稳定性进行了评价。为重点支护部位的确定提供了依据。
There is a deluvial debris near a damsite on the middle reach of the Langchang River. Its (stability) will directly influence the normal operation of the dam. This paper selects four sections of the (debris) and searches for the most dangerous slide surface. The most dangerous area is determined and its stability is analysed. The calculated results help us to find out the area that needs to be stabilized.
