Abstract

The utility model relates to an experimental device for studying rock formation loading and unloading damage, which belongs to the technical field of geotechnical engineering and coal mining experiments. The present invention comprises a frame with a front panel, a vertical loading system capable of sliding left and right is provided at the bottom of the frame; a horizontal loading system is provided in the right frame of the vertical loading system, and a The left horizontal displacement restraint plate and self-adaptive height adjustment system are installed in the left frame; the top vertical displacement restraint plate and partial pressure relief system are installed in the upper part of the frame; There is a horizontal loading plate guide platform; the lower end of the horizontal loading plate is set on the horizontal loading plate guiding platform, the left side of the horizontal loading plate is in contact with the right side of the upper vertical loading plate; the lower surface of the left horizontal displacement restraining plate is vertically loaded with the upper layer The upper surface of the plate is in contact; the lower surface on the right side of the top vertical displacement restraining plate is in contact with the upper surface of the horizontal loading plate, and its left side is in contact with the right side of the left horizontal displacement restraining plate.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering and coal mining experiments, and in particular relates to an experimental device for rock formation loading and unloading damage research. Background technique [0002] The physical and mechanical characteristics of rock units are the basis for the study of geotechnical problems. In order to solve the problems encountered in geotechnical engineering, it is often necessary to conduct experimental research on standard rock specimens at the laboratory scale, and the research types and research equipment are relatively mature. But in the actual formation, the rock structure in the formation is mostly layered structure. [0003] Laboratory experiments using standard rocks can reflect the stress and deformation characteristics of formation rock units. The effect is greater. Therefore, there is an urgent need to develop a loading and unloading experimental device for plate-shaped rock...
