利用三种D-P准则，采用强度折减有限元法并借助ANSYS软件分析了边坡的稳定性，并给出了滑裂面及安全系数，计算结果表明，滑裂面可根据土坡破坏时等效塑性区应力云图和x方向位移云图确定；用摩尔一库仑匹配D．P准则分析边坡稳定的结果与传统的极限平衡Spencer法计算结果的误差仅为1％左右，在工程计算中具有一定的实用性和可靠性。
利用三種D-P準則，採用彊度摺減有限元法併藉助ANSYS軟件分析瞭邊坡的穩定性，併給齣瞭滑裂麵及安全繫數，計算結果錶明，滑裂麵可根據土坡破壞時等效塑性區應力雲圖和x方嚮位移雲圖確定；用摩爾一庫崙匹配D．P準則分析邊坡穩定的結果與傳統的極限平衡Spencer法計算結果的誤差僅為1％左右，在工程計算中具有一定的實用性和可靠性。

The paper analyzes the stability of the slopes by using three D-P principles, the finite element strength reduction method and ANSYS software, provides the slide plane and its safety coefficient, proves by the calculation results the slide plane can be identified according to the stress nephogram of equivalent plastic zone and x-direction displacement nephogram in the destruction of the slopes, and the error of the analysis results of slope stability with the moore-coulomb matching D-P principle and the one of the traditional ultimate balance Spencer method is only 1%, so it have certain application and reliability in engineering calculation.
