摘　　要：土石坝的不饱和特性使得其渗流特性与匀质土坝有较大差异。以赛峪水库为研究对象,针对其土石混合坝的特性,采用Geo-Slope软件进行坝坡稳定计算。结果表明:通过参数设置和计算方法的选择,Geo-Slope软件可以控制并解决部分常规软件计算出现的浅表滑弧,得到与实际情况更为接近的滑弧。The instability seepage of the unsaturated soil and the steady seepage of homogeneous earth are very different.Taking Saiyu Reservoir as a research object,aiming at the characteristics of earth-rock fill mixed dam and using Geo-Slope software to calculate the dam slope stability.The results show that through the choice of parameter settings and calculation methods,Geo-Slope software can control and solve the superficial slip arc that occurred in some software calculation,sliding arc closer to the actual situation.
