摘要

Rock bursts occur when a highly stressed rock mass at depth is triggered by a dynamic disturbance. The Realistic Failure Process Analysis (RFPA) numerically simulates the occurrence of rock bursts around the deep rock tunnel, which arc triggered by a dynamic disturbance. The effects of waveforms from dynamic disturbances and tunnel depth on the occurrence of rock bursts are studied. The numerical results indicate that dynamic disturbances are one of the most important mechanisms that govern the stability of underground openings. When tensile stress induced by static in-situ stress caused by dynamic disturbance arc superposed at a location to enhance the total tensile stress, the contribution of dynamic disturbance to trigger rock bursts becomes greater with the increase of tunnel depth.
