Influence of TBM Driving Speed on Rock Burst in Deep-buried Tunnel

Based on a TBM tunnel construction project, FLAC^3D is used to simulate TBM construction. According to TBM construction characteristics, the largest unbalanced force release rate is used to realize the simulation of TMB construction speed. According to the influence of different speed on the energy indicators in rock burst, it is found that the increased TBM construction speed can reduce the risk of rock burst within a certain range, and beyond this range to increase the construction speed had little effect on the occurrence of rock burst.
