Abstract

The invention provides an airbag-type confining pressure loading system used for high-definition image reconstruction and matched with an industrial CT machine, which belongs to the technical field ofrock and soil mechanics. The airbag-type confining pressure loading system comprises an airbag pressurizing apparatus and a CT machine scanning apparatus, wherein the airbag pressurizing apparatus comprises an airbag pressure chamber, a servo pressurizing device, an upper cushion block, a lower cushion block, a connector I, a connector II, a control servo valve and a high-precision pressure gauge; and the CT machine scanning apparatus comprises a CT radioactive source and a CT detector arranged on two sides of the airbag pressure chamber. The lower part of the airbag pressure chamber is connected with the servo pressurizing device by virtue of a pressurizing device interface, the lower part of the airbag pressure chamber is connected with the high-precision pressure gauge, and the upper part and the lower part of the airbag pressure chamber are respectively provided with the upper cushion block and the lower cushion block. By utilizing the CT machine scanning technology, a deformationcracking process of a test sample in the test can be monitored in real time, and the high-definition image reconstruction of the breaking process of the test sample can be realized, so that the breaking evolution process of the loose rock and soil mass under different stress conditions and the characteristics of the rock and soil mass such as deformation and strength under different stress effects can be researched.

Description

technical field [0001] The invention relates to the technical field of rock and soil mechanics, in particular to an airbag-type confining pressure loading system used for high-definition image reconstruction and matching with an industrial CT machine. Background technique [0002] As the mining depth of open-pit mines increases, the height of slopes also increases, and instability such as landslides increases year by year. Among them, the mine dump site is a huge artificial loose slope accumulation body, and its characteristics determine that accidents such as landslides and mud-rock flows are easy to form, which are likely to cause major economic losses to the mine and endanger the life and property safety of the mine people. Therefore, it is of great significance to study the physical and mechanical properties of loose rock and soil in mine slopes and its rupture evolution process under different stress conditions. [0003] Triaxial test has always been an important resea...
