Abstract
The present invention discloses a rock mechanics experiment system for simulating deep-underground environment, including a triaxial chamber consisting of a chamber cavity and a test pedestal, a stress field building module, a high pressure seepage field building module, a high temperature field building and a seepage medium permeating control measurement module arranged in the triaxial chamber, a lifting module used for installing and disassembling of the chamber cavity, and computer module used for controlling the operation of system and calculating and outputting the test data. The lifting module includes a door-shaped support frame, a cylinder piston device vertically mounted on the door-shaped support frame beam, a coupling device and a safety suspension device. The coupling device includes an oil hydraulic rod with the upper end fixedly coupled with the piston, a safety disk fixedly coupled with the lower end of the hydraulic rod, and two symmetrically disposed coupling assemblies.
