目前，有限元强度折减法在边坡稳定分析中逐渐受到人们的重视。但是，笔者发现不同学者对于同一算例，采用同一变形参数，计算结果却不相同。于是笔者对在平面应变条件下，在边坡稳定应用中，泊松比对有限元强度折减精度的影响进行了研究。本文首先给出泊松比对安全系数的影响及折减方法，然后通过算例，证明了调整泊松比对安全系数和塑性区的分布是必要的。

At present, the application of finite element strength reduction in slope stability analysis is gradually concerned. However, the author found that for the same calculation example, by using the same deformation parameters, different scholars may obtain different results. So under plane strain conditions, in the application of slope stability, the author studied the effect of Poisson's ratio on the accuracy of finite element strength reduction. This paper gave the effect of Poisson's ratio on coefficient of safety and reduction methods, and then proved that the Poisson ratio adjustment was necessary for the coefficient of safety and the distribution of plastic zone by calculation example.
