The roof of 12501 transportation roadway of Tunlan mine is friable. To solve the problem of large roadway deformation, the bolt-mesh-anchor support scheme is put forward. With the flac3dnumerical software in the program, the simulation analysis shows that the program can effectively increase the roadway confining pressure to improve the state of the surrounding rock stress, reduce roadway displacement anddeformation and thus keep the stability of the surrounding rock. The results show that Bolt and cable support can effectively control the surrounding rock, with the roadway convergence rate small, and the support system safe.

In this paper, strain anddisplacement for flac3d numerical simulation analysis of the whole weathering granite improved soil subgrade in train dynamic load of the stress is conducted, subgrade under repeated load test data and software simulationdata is contrasted, the center of subgrade vertical settlement and the center of the subgrade stress change situation is *** the research proves the whole weathering improved soil subgrade can ensure the high-speed safety, comfort and use requirement.
