摘　　要：介绍了有限元法的优点,采用有限元强度折减法分析了某一天然边坡的稳定性,指出该法在分析边坡稳定性时考虑了土体材料的变形特性,可以很好地分析边坡的稳定性,得出的安全系数比较符合实际,计算结果比极限平衡法略大。The paper introduces the advantage of limited method, adopts the limited strength fold subtraction analyzed some the stability of the natural side slope, points out method while analyzing side slope stability considering the soil material transform the characteristic, can analyze the stability of the side slope nicely, the safe coefficient geting compares to match actual, compute result the more equilibrium than extreme limit method slightly big.
