摘要
对某高心墙堆石坝分别利用线性强度指标及非线性强度指标进行了坝坡稳定性计算分析，研究了两种强度指标下坝坡稳定性的差异。计算方法分别采用瑞典条分法和简化毕肖普法。计算结果表明：非线性强度指标计算得到的坝坡稳定安全系数总体比线性强度指标算得的大2％～20％。按照规范，该坝坡满足稳定要求。
Bsed on the dam slope stability calculation conducted for a high core wall type rockfill dam with linear strength index and nonlinear strength index respectively, the authors discuss the difference of the calculation results. Sweden slice method and simplified Bishop method are both applied. The results of calculation demonstrate that the dam stability safety factor out of the calculation with nonlinear strength index is generally 2%-20% greater than that calculated with linear strength index. The dam slope stability satisfy the requirements of relevant specification.
