Sažetak
Under the concentrated load, the tests on the brittle fracture of hinged arching until the rock-arch instability of the double-layer rock plates were conducted using self-developed loading device, and the influence factors on the rock-arch structure failure were analyzed by a numerical test based on the particle flow code (PFC). The results showed that the force-displacement curves of the double-layer rock plates displayed four phases: the small deformation elastic stage, the brittle fracture arching stage, the rock-arch structure bearing load stage and the rock-arch structure instability stage. The friction coefficient effect, cohesive strength effect of the layer between the two rock plates, and the size effect of the rock plate thickness were analyzed also. The numerical test results showed that the strain energy and strain energy entropy were consistent with the fracture instability process of the double-layer rock plates, which demonstrated that the strain energy entropy could characterize the steady state of the whole system of the double-layer rock plates.
