The zonal disintegration mechanism in rock masses around deep tunnels is totally controversial. Because this phenomenon basically depends on the stress-wave amplitude, fluctuating and declining in rock masses particularly around deep tunnels. This paper intends to theoretically solve the problem of stress-wave propagation. For this purpose, a physical model of stress-wave propagation is established in rock masses around the deep tunnels. Further, the wave equation is solved for rock masses of deep tunnels. Taking Dingji Tunnel in southern of China as a case-study, the central radius of partition is calculated theoretically and compared with the measured results in rock masses around deep tunnels. The research results of this paper gives a certain promotes to the theory of zonal disintegration in rock masses and have certain guiding significance for deep rock engineering.

The research of stress wave propagation law under cracked rock has important theoretical value and practical significance. Because of the discontinuity, nonelasticity and nonlinearity of the cracks, the theoretical interpretation and mechanism research about tress wave propagation law are a great challenge to researchers for a long time. From the establishment of the research method, the determination of mathematic model of micro-cracks and the main solutions, this paper brief reviews the current development of the influence of the complicated micro-cracks on stress wave propagation law.
