Abstract:
The evolution processes of the distortion failure of wall rock caused by the footing groove excavating at MACAU 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.
