为了提高裂隙岩体的力学性能,保证工程的质量和安全,采用水玻璃-水泥混合注浆液对裂隙岩体进行加固。通过直剪试验、显微镜实时观测试验,研究注浆结石体的强度与变形特性,以此评价水玻璃-水泥混合液作为注浆材料的可行性。试验结果表明,水玻璃-水泥混合注浆液有效的提高了裂隙岩体的力学性能。水玻璃-水泥注浆溶液不但改变了裂隙岩体的微结构、裂隙率和岩体的物质组成成分,使岩体的致密度和强度增加;而且注浆溶液在岩体结构面中凝固后对结构面进行填充加固,有效的提高了注浆结石体的黏聚力c,增强了注浆结石体抵抗外力破坏的能力。裂隙率对注浆结石体的强度影响显著,随裂隙岩体裂隙率的增加,注浆...

In order to improve the mechanical properties of fractured rock mass, to ensure project quality and safety, water glass-cement slurry injection of fractured rock mass reinforcement, by direct shear tests, real-time microscopic observations were studied strength and deformation of grouting concretion, in order evaluate water glassfeasibility cement mixture as grouting material. The results showed that water glass-cement slurry injection effectively improve the mechanical properties of fractured rock mass. Water glass-cement grouting solution not...
