Abstract

The invention relates to a rock fracture creep test system. The rock fracture creep test system comprises a man machine framework, a testing chamber, a movable mechanism, a seepage device and a displacement monitoring device, wherein the man machine framework comprises a base and a pressurizing plate; the testing chamber is mounted on the base; a cubic rock fracture test sample for testing is placed in the testing chamber; the top of the test sample is connected with the pressurizing plate; a displacement sensor is mounted on the pressurizing plate. The rock fracture creep test system providedby the invention has good sealing performance and can be used for testing rock fracture creep properties under different stress and osmosis conditions.

Description

technical field [0001] The invention belongs to the field of rock mechanics, in particular to a rock crack creep test system. Background technique [0002] In actual engineering, the creep characteristics of rock are one of the important reasons for engineering failure and instability. The study of rock creep characteristics is of great significance for the long-term reliability evaluation of rock mass engineering. Carrying out experimental research on rock creep characteristics in the laboratory can not only help us understand the creep characteristics of rocks under different stress states, but also provide basic data support for practical engineering applications. [0003] Natural rocks often contain fissures accompanied by seepage and other phenomena. These fissures are weak surfaces in the rock and play a controlling role in the overall properties of the rock. It is necessary to study the creep characteristics of rock fissures. However, although a large number of exper...
