High-temperature and high-pressure triaxial ballast rock mechanical testing device and method

The invention relates to a high-temperature and high-pressure triaxial ballast rock mechanical testing device and method, and belongs to the technical field of rock mechanical testing, the high-temperature and high-pressure triaxial ballast rock mechanical testing device comprises a box body, and a frame body is mounted on the box body; a sample bin is mounted in the frame body; an ash removal mechanism is arranged in the sample bin; a dust removal mechanism is arranged at the joint of the box body and the frame body; a dust collecting and filtering mechanism is arranged in the box body. According to the high-temperature and high-pressure triaxial ballast rock mechanical testing device and method, dust in a sample bin is rapidly treated through a dust removal mechanism, a dust removal mechanism and a dust collection and filtration mechanism, and it is guaranteed that the progress of rock testing cannot be delayed due to dust removal; meanwhile, the test accuracy can be guaranteed through the clean interior of
