通过对南宁良庆大桥北岸锚碇深基坑边坡的工程地质条件、水文地质条件、土的物理力学参数等因素的综合研究，采用理正岩土软件对基坑边坡稳定系数进行计算，结果表明，暴雨工况下边坡不稳定。选用最具代表性的剖面采用 FLAC3D进行数值模拟，得到最大不平衡力收敛曲线，模型水平、铅直和剪切3个方向的应力和位移云图，分析总结了该边坡内部应力的平衡状态以及边坡的滑坡机理，并提出了相应的边坡治理措施。

This paper conducted comprehensive study on factors such as engineering geological and hydrogeo-logical conditions of and physical mechanic parameters of soil of the slope of position holding deep foundation pit on north bank of Liangqing Bridge in Nanning and it calculated the slope stability coefficient of the foun-dation pit by applying Lizheng Geological Structure Designing software.The results showed that the slope was not stable under the condition of heavy rain.The author selected the most representative profile to con-duct numerical simulation by FLAC3D ,and the maximum unbalanced force convergence curves as well as the cloud chart of stress and displacement in three ways of horizontal,vertical and shear directions were calculat-ed.The paper analyzed and summarized the equilibrium state of the slope internal stress and the landslide mechanisms of slope,and it proposed relative slope treatment measures.
