摘　　要： 采用FLAC3D有限差分法对绿春县把不粗梁子挖方边坡稳定性进行研究,通过建立非均质三维模型,分析把不粗梁子在开挖前后的位移变形量,以及天然、降雨情况下的应力分布状况;对应力集中区采用极限平衡法计算其稳定性系数。综合有限差分法和极限平衡法计算结果,对把不粗梁子挖方边坡提出防治措施及建议。 By applying FLAC3 Dfinite difference method,this paper conducted analysis on the stability of excavation slope in Babuculiangzi area in Lvchun County.It also assessed the displacement deformation before and after the excavation in Babuculiangzi as well as the stress distribution under natural and rainfallconditions through 3-dimensional heterogeneous model.The authors calculated the coefficients of stability by applying limit equilibrium method in stress-concentrated area.By combining the results of both the finite difference method and the limit equilibrium method,the authors put forward the controlling measure and suggestions in the works of excavation slope of Babuculiangzi.
