Problems solved by technology

[0004] The disadvantage is that the inventor who proposed the true triaxial instrument did not realize that the mechanical properties of the springs in use will decrease rapidly over time, which will lead to the attenuation of the triaxial pressure on the rock sample during the test. , which destroys the test conditions, resulting in the inability to accurately simulate the field environment in which the rock is located

Abstract

The invention discloses a true triaxial test system for testing rock. The true triaxial test system comprises a main machine framework, wherein a work cavity is formed in the main machine framework, atesting chamber for accommodating a rock sample to be tested is arranged in the work cavity, and a plurality of the lateral sides of the testing chamber abut against the work cavity of the main machine framework. The true triaxial test system further comprises a plurality of sets of compensation type pressurizing devices, wherein the pressurizing devices are sleeved in the work cavity and act onthe testing chamber. At least one set of the compensation type pressurizing device is arranged on any lateral side not abutting against the work cavity of the main machine framework of the testing chamber, the compensation type pressurizing devices are used for exerting constant acting force in one direction on the rock sample in the testing chamber, and constant acting force generated by the different sets of the compensation type pressurizing devices on the rock sample in the testing chamber surround the periphery of the rock sample in the testing chamber; thus, a relatively-stable pressureenvironment can be provided, and a simulation test environment can be truer.

Description

technical field [0001] The invention relates to a true triaxial test system for testing rocks and a realization method thereof. Background technique [0002] In deep rock mass engineering, due to the interaction of geothermal, groundwater, stress and chemical reactions, there are extremely complex temperature fields, seepage fields, stress fields and chemical fields in the rock mass. At present, the research on the multi-field coupling process inside the rock mass has become one of the most popular topics in the field of rock mechanics in the world. It has extremely important scientific significance and engineering application value. Constructing the stress, seepage, temperature and chemical environment of the actual deep rock mass in the laboratory, and carrying out indoor experiments under various conditions is an important way to understand the long-term evolution of various properties of rocks under the coupling of multiple fields . [0003] For this reason, the Chine...
