介绍注浆加固前后破裂岩块的力学性能试验,结果表明注浆可以提高破裂岩块的残余强度,同时改善其侧向变形和径向变形的协调性能,从而在较大变形范围内保持稳定的承载能力,并有利于形成承载结构.试验结果进一步揭示了巷道围岩注浆加固机理.
The mechanical tests of the fractured rock mass before and after grouting reinforcement are introduced. The results show that the grouting can improve the residual strength of the rock mass, and improve the coordination performance of the lateral deformation and radial deformation so as to maintain the stability within the larger deformation range Bearing capacity, and is conducive to the formation of bearing structure.The test results further reveal the grouting reinforcement mechanism of roadway surrounding rock.
