Advanced geomechanical model test system

Abstract

The invention discloses an advanced geomechanical model test system. The system comprises a model test bench device system, a hydraulic loading system and a strain displacement test system. The modeltest bench device system comprises a bottom plate. A plurality of bottom plate cross beams are evenly arranged at the bottom of the bottom plate, a plurality of bottom plate cross beam connecting plates are evenly arranged at the bottoms of the bottom plate cross beams, bottom plate clamping plates are arranged on the side wall of the bottom plate, four stand columns are evenly arranged at the positions, close to the four corners, of the top of the bottom plate, and cross beam stand column connecting plates are fixedly connected to the tops of the stand columns. According to the invention, thestability simulation of the excavation process of underground geotechnical engineering such as tunnels (pits), underground engineering caverns and the like can be effectively completed, the anchor rod (cable) support can be simulated, the stress and displacement in the tunnel surrounding rock can be analyzed, the tunnel surrounding rock fracture can be studied, and the reinforcement measures canbe optimized.

Description

Technical field [0001] The invention relates to a geomechanics model test system, specifically an advanced geomechanics model test system. Background technique [0002] From the beginning of the 20th century, some countries in Western Europe began to carry out structural model tests and gradually established similar theories. In the 1960s, experts led by E. Fumagalli pioneered the engineering geomechanics model test technology at the Italian Structural Model Test Institute. The test research ranged from elasticity to plasticity to the final failure stage. Subsequently, Portugal, the former Soviet Union, France, Germany, the United Kingdom, and Japan also carried out research in this area. In China, since the 1970s, Wuhan University of Water Conservancy and Electric Power, Tsinghua University, the Three Research Institutes of Engineering Corps of the General Staff, Southwest Jiaotong University, and China University of Mining and Technology have successively conducted geomechanic...

Problems solved by technology

[0003] However, the current geomechanical model test systems for simulating underground rock and soil tunnels are mostly fixed in size, with a small scope of application and poor scalability. It is impossible to add other loading devices on the basis of the existing models.
