Wave Equation in Rock masses with numerical modelling

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 rock mass around deep circular tunnel under dynamic disturbance. Numerical tests presented thedistribution of stress and deformation and visualized zonaldisintegration 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
