Rock mass shear test system for high energy accelerator ct scan

Abstract

The invention belongs to the technical field of rock mechanics tests, and aims to solve the problem that the progressive failure process of rock shear cannot be accurately scanned, and specifically relates to a rock shear test system for high-energy accelerator CT scanning, including double-level loading device, the first bearing device for carrying the static shear box, the second bearing device for carrying the dynamic shear box, and the normal loading device; Apply shear force to the loading device for the rock mass; through the parallel interval setting of the double-level loading device and the loading method of applying the loading force in the horizontal direction and applying the shear force in the vertical direction, it can effectively realize the accurate scanning of the rock mass shear progressive failure During the process, the loading cylinder and the rock mass sample do not interfere with each other. Through the present invention, a new rock mass shear test system combined with CT scanning technology can be provided, thereby providing key technical support for realizing visual detection in the rock mass shear progressive failure process.

Description

technical field [0001] The invention belongs to the technical field of rock mass mechanics tests, and in particular relates to a rock mass shear test system used for high-energy accelerator CT scanning. Background technique [0002] A rock mass is a geological body consisting of rock blocks and structural planes. The shear strength characteristic of rock mass is a key index to evaluate its stability. Under the action of shearing, the rock mass will produce a progressive failure process of crack initiation, crack initiation, expansion and penetration. Quantitative description of the progressive shear failure process of rock mass is very important to determine the shear strength characteristics of rock mass. [0003] Existing research mainly adopts two methods of indoor experiment and numerical simulation. During the indoor test, the time and space information of crack generation and development in the process of rock mass shear progressive failure can be obtained indirectl...
