Device and method for testing impact shear resistance of concrete-rock interface for Hopkinson pressure bar

The invention discloses a device and method for testing the impact shear resistance of a concrete-rock interface of a Hopkinson pressure bar, the device comprises a lower shear box fixed on an equipment support through a fixing device, the lower shear box comprises two steel plates which are symmetrically arranged, one steel plate is a lower shear box slidable steel plate, and the other steel plate is a lower shear box sliding steel plate. The other block and the fixing device are integrally arranged; an upper shear box is arranged above the lower shear box and comprises two steel plates which are symmetrically arranged, an incident bar is arranged on the outer side of one steel plate, and a transmission bar is arranged on the outer side of the other steel plate. Compared with the prior art, the device has the following advantages that the overall structure is optimized, a detachable mounting mode is mostly adopted, and the incident bar and the upper shear box are integrally arranged, so that the incident bar
