A Study of Application about FLAC-3D in Damage of Rock Mass Slope

Abstract:

A damage mechanics model for jointed rock mass is established by the simulation of the multi-cleavage behaviour by introducing the damage tensor and by considering the jointed rock mass as continuous medium with damage. The data exchange technique with FLAC-3D is discussed by applying FISH Language that is inserted in FLAC-3D. The coupling analysis between the rock mass damage and FLAC-3D is realized by the computer program for damage mechanics analysis set up by Visual Basic, which is applied in the simulation analysis of the south slope of Yanqianshan Iron Mine.
