Triaxial test device and method capable of applying dynamic and static combined load and impact load

The invention relates to the technical field of rock mechanics, in particular to a triaxial test device and a triaxial test method capable of applying dynamic and static combined load and impact load. When a specific mechanical property test of coupling static load, dynamic load and impact load is carried out, a confining pressure value is applied according to the crustal stress of a rock sample occurrence environment; after static axial stress is applied to the size of vertical ground stress, the confining pressure and the axial pressure are kept unchanged in the whole test process; applying a dynamic load according to a certain loading period, selecting the waveform of the dynamic load in advance, and applying an impact load at a certain time interval to obtain a rock stress-strain curve under the coupling action of the static load, the dynamic load and the impact load; therefore, the problem that an existing rock mechanics test device is relatively single in research mode is solved. 本发明涉及岩石力学技术领域，具体涉及可施加动静
