[0004] "Rock and Soil Mechanics" No. 7, 2009 introduced a physical model test for the stability of anisotropic rock mass tunnels with gently dipping angle bedding. The layered rock mass was generalized into a layered model, and the interlayer of the model was adopted The extremely soft film partition realizes delamination, but the method only realizes the bedding with a gentle dip angle, and the thickness of each rock layer cannot be guaranteed to be equal, and the loading method is the plane strain loading method
[0005] "Journal of Rock Mechanics and Engineering" No. 8, 2013 introduced a model test device for the influence of stick-slip dislocation of normal faults with a 75° dip angle on highway tunnels. Forced displacement is imposed on the bottom of the box to simulate the dislocation of faults and realize the tunnel in the fault. Force and deformation research under influence, but only a single fault can be simulated, and three-dimensional loading cannot be realized
[0006] "Journal of Coal Science" No. 7, 2013 introduced a simulation test of stratum movement in the mining of ultra-thick and steeply inclined coal seams. Inclined coal seams with different thicknesses were prepared, and the characteristics and characteristics of stratum deformation and failure during stratified mining of ultra-thick coal seams with an inclination angle of 50° were revealed. mechanism, but the experimental device did not carry out layered compaction of inclined coal seams, and did not realize true three-dimensional loading
[0007] "Rock and Soil Mechanics" No. 10, 2016 introduced a mode

Description
technical field [0001] The invention relates to a physical model test device and method for inclined rock formations, in particular to a physical model test device and method for inclined rock formations with different dip angles in underground engineering. Background technique [0002] With the rapid development of underground engineering construction, underground engineering continues to go deep, and the surrounding rock environment is becoming more and more complex. Under the action of in-situ stress and external forces, the underground rock formations form inclined distribution rock formations. In order to ensure the excavation and operation of engineering construction in inclined rock formations Safety, the study of physical and mechanical properties such as deformation and failure of rock formations and stress-displacement changes of surrounding rocks has become an important topic in the field of geological and rock formation research. However, due to the complex and c...
