Abstract

A triaxial rock mechanics test system for high-strain-rate cyclic dynamic loading is provided, including: a host loading module, a dynamic cyclic loading module, and a dynamic measurement module. The host loading module includes a loading frame, a triaxial pressure mechanism and an actuator that are provided inside the loading frame. The dynamic cyclic loading module includes a driving mechanism, a fixed mechanism and a mobile mechanism. The dynamic measurement module is configured to acquire axial pressure data, radial deformation data and axial deformation data of the rock sample during a test. In the triaxial rock mechanics test system for high-strain-rate cyclic dynamic loading of the present invention, an energetic rod is driven by an electrical explosion of a metal wire to generate a strong shock wave with controllable peak pressure, duration and waveform.
