摘 要: 应用自行开发的岩石破坏过程分析软件F RFPA2D对澳门某基坑开挖引起围岩及地表变形破坏进行了数值模拟分析 ,认清了围岩破坏模式及发展全过程 ,得到了和实际情况基本一致的结果 ,说明了F RFPA2D程序做为一种新的数值模拟方法 ,可以用来研究基坑、边坡开挖引起的围岩破坏过程。 The evolution processes of the distortion failure of wall rock caused by the footing groove excavating at Macao is analyzed by numerical simulation code,Wall Rock Fracture Process Analysis(F?RFPA 2D ),which is developed by ourselves.The numerical simulation explains the evolution process and pattern of wall rock mass fracture,gains a accordant result with the actually,F?RFPA is a new numerical method to study the problem of Wall Rock Fracture caused by the slope and footing groove excavating.
