Abstract：The zonal fracturing mechanism and its failure criteria in deep tunnel were put forward, and the phenomenon of zonal fracture was reproduced using numerical simulation. Found that zonal fracture is not completely continuous cir-cular ring, but the breakdown of isolated regions, and from this merge into zonal product. The relationship between zon-al fracture and rock burst was put forward, and rock burst breeding process to its occurrence were explained from the zonal fracture phenomenon, and provided a new way of thinking for rock burst generating mechanism.
