Abstract

During the excavation of rock mass with the method of drill and blast, the release of in-situ stress, also known as excavation load on boundary, is traditional a dynamic process, so the inertia and all other dynamic responses induced by the release of in-situ stress cannot be ignored. Compared with corresponding quasi-static unloading, dynamic displacement field of surrounding rock is decomposed into the quasi-static displacement and the dynamic displacement. Disturbance in the surrounding rock increases with a decrease in unloading rate.
