摘要
针对极限平衡法对边坡进行稳定分析时不能解决边坡分析的变形问题。利用FLAC3D软件内嵌的强度折减法对某一土质边坡进行数值模拟。通过模拟可以得到边坡的安全系数以及边坡土体的应力场、位移场的变化规律,得出最大位移所在的位置。结果表明,FLAC3D在解决边坡稳定分析的变形方面有着较大的优势。
When limit equilibrium method was used to analyze the stability of slope,the deformation problem of slope analysis could not be resolved.The strength reduction method in the FLAC3D was used to numerical simulate a soil slope.By the numerical simulating,the safety factorof slope,variable law of soil＇s stress field and displacement field were gotten,and then position of the maximum displacement was reached.It was indicated that FLAC3D has some advantage on the stability analysis of slope.
