摘　　要：土石坝稳定分析采用线性和非线性抗剪强度指标进行计算,其结果尚存在很大的差异,不仅计算安全系数结果不同,而且滑弧位置也有很大不同。因此,非线性稳定分析尚应进一步研究。There are larger discrepancies in the results from the calculations of the stability analyses on rock-earthfill dams made with linear or nonlinear shear strengths, not only the results from the calculations of the safety coefficients are different, but the positions of slip circles are also dissimilar. Consequently, the nonlinear stability analysis for rock-earthfill dam is to be studied at present.
