摘　　要：以某水电站高边坡为研究对象,运用刚体极限平衡法计算分析该边坡崩塌堆积体的稳定性,研究认为对边坡影响较大的堆积体底界接触带、t1c、t3和t2等结构面的工程勘察强度参数偏低,与实际情况不符。对边坡岩体的强度参数进行反演,提出比较符合实际的强度参数,为工程边坡处理提供可靠依据。Taking a high slope of a hydropower station as the research object, the stability of the collapsed deposit body of the slope is calculated and analyzed by rigid limit equilibrium method. It is considered that the engineering investigation strength parameters of the bottom contact zone, t1 c, t3 and t2 structural planes of the deposit body, which have great influence on the slope, are on the low side. And this result is not in conformity with the actual situation. The strength parameters of slope rock mass are inverted, and the more realistic strength parameters are put forward, which provides a reliable basis for the treatment of engineering slope.
