Problems solved by technology

To measure different rock samples, it takes a long time to load and unload the samples each time, and the confining pressure chamber needs to be recharged and unloaded each time, resulting in low test efficiency
When performing seepage tests on different rock samples, it is also necessary to continuously load and unload the samples, resulting in low test efficiency

Abstract

The invention provides a wheeled THMC-rock multifunctional tester and a wheeled rock test method and relates to the field of rock mechanics tests. The wheeled THMC-rock multifunctional tester comprises a vertically-arranged sleeve; the sleeve, a top cover and a base jointly form a confining pressure chamber; an oil inlet and an air exhaust hole are formed in the confining pressure chamber; an axial force loading rod is vertically inserted into the top cover; downward loading force can be applied to the bottom end of the axial force loading rod; a fluid channel is formed in the axial force loading rod; a horizontally rotatable turntable is arranged in the confining pressure chamber; along with the rotation of the turntable, the bottom end of the axial force loading rod and the fluid channelpoint to different positions of the turntable. The wheeled THMC-rock multifunctional tester can load a plurality of rock samples and complete medium temperature-seepage-stress and chemical coupling tests of the different rock samples, so that the rock triaxial test efficiency is greatly improved. The wheeled rock test method based on the wheeled THMC-rock multifunctional tester is simple and highin test efficiency.

Description

technical field [0001] The invention relates to the field of rock mechanics tests, in particular to a wheeled THMC-rock multifunctional tester and a wheeled rock test method. Background technique [0002] Rock triaxial test is an important means to study rock mechanics, it can relatively completely simulate the mechanical properties of rock and soil under the original stress state, and it is an important basis for engineering design. Because the deep rock is in a complex stress state, the rock mass or ore body encountered in mining engineering is mostly in a three-dimensional stress state, and it is a very complex natural material. In many cases, rocks in a simple stress state Stress tests cannot fully reflect the stress state of rock mass in engineering practice, and the mechanical properties of rock under complex stress states must be fully understood. Therefore, it is very important to carry out rock test research under the triaxial state. [0003] The rock triaxial tes...
