Abstract: The forming process of the layered crack and failure structure and effect of the disturbing stress wave intensity pmax on the forming of the layered crack and failure structure is simulated in software LS-DYNA. The characters of the shape and thickness of the layered crack structure of the surrounding rock in the roadway-rib are acquired. It shows the stress wave disturbance is an important factor to form layered crack and failure structure and induce the rockburst; and intensity of the stress wave decides whether the layered crack and failure structure is formed and how for the structure grows. It has an important significance of researching the mechanism of inducing rockburst and taking effective measures to control rockburst.

Key words: stress wave, surrounding rock of roadway, layered crack and failure structure, rockburst, numerical simulation
