Abstract

Numerical tests on three-dimensional rock samples containing hole were carried out with finite element software ANSYS to investigate the mechanism of zonal disintegration within surrounding rockmass around deep circular tunnel under dynamic disturbance. Numerical tests presented the distribution of stress and deformation and visualized zonal disintegration phenomenon of rockmass around deep semiarched tunnel under dynamic loads. The simulation results indicate that zonal disintegration phenomenon may occur, when superposition value of high ground stress and dynamic disturbance satisfies a certain condition.
