Abstract
A rock mechanics test system with impact loading-confining pressure unloading and its usage method. The test system includes bearing frame unit, axial compression loading unit, impact loading unit and confining pressure loading unit. The bearing frame unit includes pedestal, column and cross beam. The column is vertically installed on both sides of the upper surface of the pedestal, and the cross beam is horizontally fixed on the upper part of the column. The axial compression loading unit is fixed at the middle position of the upper surface of the pedestal and is used to exert the axial bottom-up pressure to the sample. The impact loading unit is fixed on the cross beam and is used to exert the axial top-down impact load on the sample.
