Bearing frame for simulating stress state of deep rock mass

Abstract

The invention relates to a bearing frame for simulating a stress state of a deep rock mass. The bearing frame is a rectangular cavity with flexible capsules; a rectangular rock mass test piece is fixedly arranged in the cavity; the flexible capsules are respectively arranged between each side surface of the rock mass test piece and the corresponding cavity wall, which is opposite to the side surface, of the cavity; each flexible capsule is provided with at least one guiding pipe; high-pressure liquid enters the flexible capsules through the guiding pipes, so that the rock mass test piece can be loaded, and simulated high-ground stress can be generated by the rock mass test piece. The bearing frame disclosed by the invention has the beneficial effects that the test piece is loaded by adopting the flexible capsules, stress can be very smoothly and evenly applied to the test piece, a high-ground stress state of the deep rock mass can be well simulated, and the structure of a loading mechanism can be simplified.

Description

technical field [0001] The invention relates to a simulation device of a stressed state, in particular to a bearing frame for simulating a deep rock mass stressed state. Background technique [0002] At present, my country's transportation, water conservancy and hydropower, energy, mines, and military protection all have problems involving deep underground engineering, and deep rock mass exists in a high-stress environment. The risk of disasters such as partition rupture, large deformation, rockburst, and engineering earthquake occurs. Therefore, in order to prevent the occurrence of the above-mentioned disasters, relevant scholars and experts at home and abroad are conducting in-depth research on deep rock mass engineering and simulating the stress state of deep rock mass. However, the current simulation is limited to the simulation of high ground stress, or the simulation of high ground stress and excavation disturbance, and there is no bearing frame for the simulation dev...
