摘要:
根据现场取样分析和实验分析探讨了围岩注浆堵水隔障机理，注浆浆液充填了岩石孔隙、溶隙等空隙，使岩石的宏观孔隙度降低、致密程度增加，改变了岩石的物力性质，使岩石由原来的含水层或透水层变为隔水层；对注浆前后岩石进行了单轴压缩试验，通过对比实验分析研究，结果表明浆液在岩体结构面中凝结后对结构面进行充填加固，使注浆岩体的单轴抗压能力提高，能在较大变形范围内保持稳定的承载能力，增强了工程岩体抵抗外力破坏的能力。注浆隔障带能够承受水压能力增大，隔水性能增强；并从理论上对固结体的强度进行了分析计算。
Abstract:
According to analysis of the scene sampling and test mechanism of wall rock grouted pluging up water is discussed. Grouting slurry filled the rock pores, which made rocks macrography porosity decrease and compactness increase, the material changed the nature of the rock so that rock turned from the aquifer or aquitard into impermeable layer.Two kinds of rocks consisting of ungrouted and grouted were taken by uniaxial compressed tests, It showed that the grouted rock massed the structure after condensation by comparing the experimental analysis results.Medium coagulated for filling of the structure reinforcement,so that the uniaxial compressive rock grouting ability was improved to maintain stability of the carrying capacity to under deformation in the larger framework and to enhance the engineering rock mass resistance to undermine the ability of external forces.Grouting separated with impaired ability to withstand water pressure would increase, and impermeable performance would enhance, The stren
