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 rocks under the actions of high temperature and seepage. The true-triaxial test system comprises a host framework, wherein a working chamber is formed in the host framework; a test chamber for putting a to-be-tested rock sample is arranged in the working chamber; a plurality of side faces of the test chamber are supported against theworking chamber of the host framework. The true-triaxial test system further comprises at least several sets of compensative pressurizing devices which are arranged in the working chamber in a sleeving manner and act on the test chamber, a constant temperature device and a seepage device; the true-triaxial test system can provide a relatively-stable pressure environment, simulates a test environment more really and realizes an effect of implementing the test under the actions of the high temperature and the seepage.

Description

technical field [0001] The invention relates to a true triaxial test system for testing rock under high temperature and seepage action. 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, t...
