Abstract: A clamp and a shear test device are provided, and relate to the technical field of rock mass mechanics tests. The clamp comprises a box body, wherein an opening is formed in one side of the box body, two clamping structures are oppositely arranged in the box body, a sample is arranged between the two clamping structures, each clamping structure comprises an adjusting mechanism, and a distance between the two clamping structures is adjusted through adjusting mechanisms of the two clamping structures. According to the clamp, real-time dynamic adjustment is conveniently and rapidly achieved, the stability of sample clamping is ensured, and therefore the requirement that the shear load can be truly and effectively transmitted to the sample through the box body is met.

Abstract: A rock mass shear test system for high-energy accelerator computed tomography (CT) scanning includes double horizontal loading devices, a first bearing device for bearing a static shear box, a second bearing device for bearing a dynamic shear box, and a normal loading device, etc. In the test, the double horizontal loading devices simultaneously apply an identical loading force to the rock mass, and the normal loading device applies a shear force to the rock mass. The double horizontal loading devices are provided in parallel and spaced apart, a loading force is applied in the horizontal direction, and a shear force is applied in the vertical direction, so that the loading cylinder and the rock mass sample are effectively prevented from interfering with each other during the accurate scanning process of the shearing progressive failure process of the rock mass.
