Description

Technical field[0001]The invention relates to a high-temperature and high-pressure rock triaxial experimental device matched with CT online scanning, which belongs to the technical field of rock experimental devices.Background technique[0002]High temperature and high pressure rock mechanics is an important research content of rock mechanics. With the improvement of the research on the macro-mechanical properties of rock materials, the meso-rock mechanics based on the rock mesostructure and its crack evolution and incubation process under the conditions of high temperature and high pressure and its influence on the mechanical strength and seepage characteristics of rock becomes rock mechanics. New trends in development. The high-temperature rock triaxial online CT scanning experimental device can realize the direct observation of the pores and fissures in the rock at the meso-scale. It is an important means and instrument for studying the mechanical properties and seepage characteris...
