Crack-containing rock material preparation test device and use method

Abstract

The invention discloses a crack-containing rock material preparation test device and a use method. The crack-containing rock material preparation test device comprises a bottom plate, a static side plate and a movable side plate, the static side plate is fixed on the bottom plate, the side end of the static side plate is connected with one side of the triangular auxiliary baffle, and the other side of the triangular auxiliary baffle is fixed on the bottom plate; the movable side plate is movably arranged on the bottom plate, and a crack placement cavity is formed between the movable side plate and the static side plate; the static side plate and the movable side plate are provided with at least one group of crack placement structures; the fracture placement structure comprises at least one group of fracture structures, and the fracture structures are located in the fracture placement cavity; connecting pieces used for limiting displacement of the movable side plate in the horizontal direction are arranged at the connecting positions of the static side plate and the movable side plate. The triangular auxiliary baffle is provided with at least two adjusting bolts, and the adjusting bolts penetrate through the triangular auxiliary baffle and are in contact connection with the movable side plate. Compared with traditional rock-like modeling equipment, the modeling equipment has more flexible model size control capability, and is convenient to demould and simple to operate, and the modeling equipment is long in service life and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of rock material preparation, and in particular relates to a test device for preparing rock materials containing cracks and a method for using the same. Background technique [0002] Due to physical effects such as weathering, erosion, and shear dislocation between the jointed rock walls, a certain thickness of backfill will be produced in the rock joints to form backfill rock joints, which are widespread in natural rock masses. Due to the difficulty of on-site sampling, high cost and discreteness of natural backfill rock joint specimens, it is also very difficult to accurately measure the thickness of the filling medium between the upper and lower surfaces of natural backfill rock joint specimens. Using rock-like materials to prepare artificially simulated rock joint specimens with the same rock strength and surface morphology as actual rock joints is a commonly used sample preparation method in the rock me...
