摘　　要：反倾互层边坡在岩层倾向与边坡坡向组合上存在特殊性,边坡开挖对反倾向边坡稳定性有一定影响。结合西南某大型水电站边坡开挖实际,通过选取其主剖面,利用物理模拟研究方法中的底摩擦试验,对这个问题进行了探讨,对给出直观确定合理开挖坡比,以及确定开挖松弛区范围的方法都具有重要意义。Antidip rock slopes have their particularity in terrain tendency. There are some effects on the stability consequent an- tidip rock slope by cutting. Based on one high steep dipslope in one hydropower station,by choosing the main section of the slope and using the experiment.of basal contract friction in physical simulation methods,this problem is synthetically analyzed. The result will be devoted to confirm the angle of slope excavation and determine relaxation region.
