Study on wave propagation law of blasting stress and crack evolution characteristics of granite with weak interlayer
To investigate the influence of weak interlayers in rock mass on the propagation law of blasting stress waves and the propagation characteristics of rock mass blasting cracks, numerical simulation methods were used to study the propagation law of blasting stress waves and the propagation characteristics of rock mass damage cracks in granite tunnels without and containing weak interlayers, based on a certain excavation project of a granite tunnel containing weak interlayers. The research results indicate that when there are weak interlayers distributed around the blast hole, on the one hand, the weak interlayers will have a blocking and reflecting effect on the blasting stress wave, and on the other hand, the existence of weak interlayers will change the evolution direction of rock blasting cracks, which is manifested as over-excavation in the weak interlayered area in engineering. The research results can provide guidance for the design of tunnel blasting parameters with similar adverse geological conditions.
