The heating structure is disposed in the test chamber, the water supply structure is connected to the test chamber, the water supply structure is used to supply water to the test chamber and immerse the heating structure, and the drainage structure is connected to the test chamber. A pressure assembly, a portion of which extends into the test chamber, abuts against the surface of the test rock mass to apply pressure to the test rock mass; A gas assembly, connected to the test chamber, is used to supply test gas to the test chamber; The controller is electrically connected to the heating and humidifying component, the pressure component, and the gas component. The controller is used to control the opening and closing of the heating and humidifying component and the gas component. The controller is also used to control the pressure of the pressure component.

2. The rock mass testing device of claim 1, wherein: The water supply structure includes a water supply pipe and a water supply valve. The water supply pipe is connected to a water source, and the water supply valve is electrically connected to the controller. The controller is used to control the opening and closing of the water supply valve.

3. The rock mass testing device of claim 2, wherein: The water supply structure also includes a water pressure sensor, which is connected to the water supply pipe and electrically connected to the controller. The controller is used to adjust the opening and closing of the water supply valve according to the pressure detected by the water pressure sensor.

4. The rock body testing apparatus of claim 1, wherein: The pressure assembly includes a push rod and a hydraulic servo device that drives the push rod to move. The push rod abuts against the surface of the test rock mass to apply pressure to the test rock mass, and the hydraulic servo device is electrically connected to the controller.

5. The rock mass testing device of claim 4, wherein: The pressure assembly also includes a push plate connected to the end of the push rod away from the hydraulic servo device, the push plate being used to contact the test rock mass.

6. The rock mass testing device according to any one of claims 1 to 5, characterized in that: The test chamber includes a base, side walls, and a cover plate. A test platform is protruding from the upper surface of the base. The test platform is used to place and fix the test rock mass. The side walls surround the outer periphery of the base, and the cover plate covers the top of the side walls. The outlet of the water supply structure and the inlet of the drainage structure are both located on the base. The cover plate has a through hole that connects to the test chamber. The through hole corresponds to the test bench. A part of the pressure component passes through the through hole.

7. The rock mass testing device of claim 6, wherein: The through hole is provided with a sealing structure, which seals the gap between the pressure component and the through hole.

8. The rock mass testing device of claim 6, wherein: The gas assembly includes an intake pipe that passes through the side wall and connects to the test chamber to supply test gas to the test rock mass.
