Problems solved by technology

[0002] Coal and rock are natural geological bodies, which have been subjected to in-situ stress for a long time. Artificial excavation and disturbance will lead to corresponding changes in in-situ stress, which has a great impact on the permeability of coal and rock. To study the influence of stress on the permeability of coal and rock It is the key to the stability analysis of rock engineering, coal seam gas drainage and disaster prevention and other projects. The existing triaxial stress seepage test device is not easy to measure accurately, and the test process is complicated. Axial stress seepage test system

Abstract

The invention discloses a CT technology-combined triaxial stress seepage test system. The system comprises a fixed pedestal, a triaxial pressure bin is fixedly arranged in the middle of the fixed pedestal, a plurality of CT scanners are fixedly arranged surrounding the triaxial pressure bin, and the CT scanners are arranged on the fixed pedestal through mounting racks. The fixed pedestal is provided with the triaxial pressure bin, a liquid storage chamber is arranged in the triaxial pressure bin, an axial pressure chamber is arranged above the liquid storage chamber, a confining pressure chamber is arranged at the side surface of the liquid storage chamber, air inlet tubes are arranged in the axial pressure chamber and the confining pressure chamber, air blowing pumps are arranged at the tail ends of the air inlet tubes, the air introduction volume is changed to realize the change of the pressure above and surrounding the liquid storage chamber, a liquid discharging tube below the liquid storage chamber is provided with a flow meter to realize the monitoring of the flow amount of a liquid, and the scanning observation of the influences of the pressure change on the permeability ofthe liquid is realized through the 360 DEG omnibearing scanning of the CT scanners.

Description

technical field [0001] The invention relates to the field of triaxial stress seepage tests, in particular to a triaxial stress seepage test system combined with CT technology. Background technique [0002] Coal and rock are natural geological bodies, which have been subjected to in-situ stress for a long time.
