摘要
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.
This paper is about mechanical property tests of broken rock before and after grouting reinforcement.Test results show that grouting can raise the remains of strength of broken rockmass.and improve the coordinated properties of lateral and vertical deformations.Thus the samples can maintain supporting capacities in large deformation's ranae.and supporting structure can be easily formed.Test results further reveal the mechanism of grouting reinforcement of surrounding rock of roadway.
