摘　　要：为使在边坡稳定性分析中提供的强度参数更加合理,对山西省各高等级公路实际工程进行了野外调查与室内试验,选取不同工程地质分区内不同边坡地层组合形式的典型边坡进行数值模拟对比分析,提出了峰值强度、启动强度、残余强度三种不同强度参数概念及获取方法,并分析了三种强度参数对边坡稳定性的影响,最后对山西省边坡强度参数选取提出了合理建议.In order to actual engineering of provide more reasonable strength parameters in the slope stability analysis, the high grade highway in Shanxi province was field-investigated and many laboratory tests were executed. We chose typical solpes from different engineering geological zon- ing and different slope formation combination to compare and anysis for the numerical simulation, put forward the concept and acquisition methods of peak intensity, starting strength and residua strength, and analyzed the influence of three strength parameter on the slope stability. Finally, we proposed reasonable proposals on Shanxi slope strength parameter selection.
