In order to study the three dimensional stability of one large underground stope after excavation, the numerical simulation software FLAC3D is used to calculate the deformation and failure situation of the surrounding rock mass. The calculations are done for two cases of whether penetration taking place in the goaf. During calculation the effects of(More)
Simplified mechanical model can not reflect the real situation of the interaction between foundation and cables. Then numerical software FLAC3D is used to simulate the procedure of foundation excavation and cable reinforcement. Deformation responses of foundation are analyzed as well as the mechanical response of cables. The results show that, (1) the(More)
