摘　　要：基于ANSYS的岩土分析计算能通过强度折减使系统达到不稳定状态。使用ANSYS对某一边坡进行稳定性分析,结果表明:随着折减系数的不断增大并达到某一数值时,边坡内塑性应变自坡底向坡顶贯通,边坡达到极限状态,此时的折减系数即为安全系数,有限元强度折减法对边坡稳定性分析具有良好的适用性。Based on the great geotechnical analyzing function of ANSYS, through strength diseourt, to make the system instability, limited element count will not convergence, so the discount coefficient is safty coefficient. By using ANSYS to make stability analysis of a slope, the result shows that with the eontinueus enlange of discount ratio and then get some number, the slope get the limited spot, and we get the salty coefficient. Limited element count has great applicability of slope stability analysis.
