摘要
The present invention discloses a device, system and method triaxial compression test with/without jacket by gas confining pressure on rock, and belongs to the technical field of rock mechanics tests. The device includes a container, wherein an accommodating cavity is disposed in the container for placing a core sample, a first through hole and a second through hole are respectively disposed at an upper end of the container, the first through hole is used for penetration of an end cap for loading an axial pressure to the core sample, the second through hole is used for injecting a gas into the accommodating cavity so as to apply a gas confining pressure on the core sample, a third through hole is disposed at a lower end of a side wall of the container, and the third through hole is used for communicating the accommodating cavity with the triaxial cell so as to achieve pressure transfer and balance between the accommodating cavity and the triaxial cell. During application, the device is installed in the triaxial cell. The container is inflated by a gas inlet and outlet of the triaxial cell and a communicating tube, the internal pressure applied by a high pressure gas on a near field rock wall of a salt cave can be accurately simulated, and a triaxial compression test with/without jacket by gas confining pressure on rock is conducted.
