ABSTRACT
During the shallowly buried explosion process, a complicated energy evolves between the explosive and the rock mass. Based on the continuum-discontinuum element method and energy statistics algorithm, the energy evolution characteristic of rock mass under shallowly buried explosion loading is investigated. First, the energy statistics code is parallelized using the OpenMP technology to enhance computational efficiency, and the accuracy is verified. Then, a full-time numerical simulation of rock mass under shallowly buried explosion loading is conducted, and the change trends of various constituent energy are investigated. The numerical results show that the various constituent energy have different change trends, and the change trends are closely related to the detonation gas pressure, rock movement characteristic, and crack characteristic.
