摘　　要：采用非线性有限元强度折减法 ,对福宁高速公路A1 5 - 2标段二埔塘 2号路堑高边坡进行了稳定分析。通过对该高边坡非线性有限元模型进行强度折减 ,使边坡达到不稳定状态时 ,弹塑性有限元静力计算将不收敛 ,此时的折减系数就是稳定安全系数 。In this paper,an analysis on deep cut slope stability is carried out by nonlinear finite element strength reduction method.With strength reduction,the slope nonlinear finite element model would be in unstable state,the elastic finite element static calculation would be non-convergent.At this time,the reduction factor is just the safety factor,and the failure surface and overall failure process can be found automaticalyy.
