摘要：

Dynamic explosion of rock mass has been simulated numerically with ABAQUS/Explicit software. Elastoplastic dynamic failure constitutive models have adopted. The Jones-Wilkens-Lee (JWL) state equation has been used to calculate the pressure caused by the release of the chemical energy of explosive. Ten-sile dynamic failure criterion has been adopted as the rock failure criterion, and hydrostatic pressure has been used as the measure of spalling force. A rock specimen with denotation point set on the middle point of the borehole has been investigated numerically. Numerical results obtained with AB AQUS/Explicit have been compared with experimental phenomenon, and reasonable accordance has been observed.
