Abstract

The invention belongs to the technical field of mechanics test devices, and specifically relates to a high-energy accelerator CT rock mechanics test system. The high-energy accelerator CT rock mechanics test provided by the invention comprises a mechanics test machine, a high-energy accelerator CT ray source and a detector, the mechanics test machine is arranged between the high-energy acceleratorCT ray source and the detector, the mechanics test machine comprises a fixed component, a rotary apparatus and a pressure chamber, the rotary apparatus is arranged on the fixed component, the pressure chamber is connected with the rotary apparatus, and when a test is executed, the pressure chamber can rotate relative to the fixed component under driving of the rotary apparatus. The test machine is provided with the rotary apparatus, and when the test is executed, the pressure chamber is driven by the rotary apparatus to rotate, namely, a test sample can be scanned in a process in which a loadtest is executed for the test sample, consequently, CT imaging can completely reflect a structural state of the test sample when the test sample is loaded, and scientific researches are facilitated more.

Description

Technical field [0001] The invention belongs to the technical field of mechanical test equipment, and specifically provides a high-energy accelerator CT rock mechanics test system. Background technique [0002] The exploration and development of resources in the world today has advanced to the second depth space of the earth (2000~10000 meters). The development of such resources requires the use of ultra-deep vertical wells and horizontal wells, and the geological body must be reformed to implement rock fracturing to increase permeability. . The efficient development of this kind of resources must solve the major basic scientific problem "the fracture formation and evolution of geological bodies under the action of pressure and temperature, the gas-liquid migration law and the change characteristics of physical properties", which is also the frontier science of understanding the state of geological bodies and geological processes problem. [0003] The traditional rock mechanics t...
