Abstract
The present disclosure provides a thermal-stress-pore pressure coupled electromagnetic loading triaxial Hopkinson bar system and test method, the system mainly consists of an electromagnetic pulse generation system, a servo-controlled axial pressure loading system, a servo-controlled confining pressure loading system, a thermal control system, a pore pressure loading system, a bar system, and a data monitoring and acquisition system. Based on the conventional Hopkinson bar, the present disclosure creatively introduces a real-time loading and control system for confining pressure, thermal, and pore pressure, aiming to solve the technical problem that the existing test apparatus cannot be used to study dynamic response of deep rock mass under the coupling effect of thermal-stress-pore pressure and dynamic disturbance during dynamic impact loading.
