摘　　要：实验室测试分析和现场工业性试验研究结果表明 ,水泥注浆加固不但改变了岩石的微结构、微孔隙和岩石的物质组成成份 ,使岩石的宏观孔隙度降低 ,致密程度和机械强度增加 ;而且 ,浆液在岩体结构面中凝结后对结构面进行充填加固 ,提高了结构面的粘结力和内摩擦角 。The results of laboratory measurements and field industrial tests show that cement grouting reinforcement not only changes the microstructure, microporosity and composition of rock, making its macrography porosity decrease and compactness and mechanical strength increase, but also fills the structure surface of engineering rock mass after grouting, leading to the structure surface’s adhesion and frictional coefficient to enhance. The last result of those effects is the engineering rock mass ability of resistance to force damage is increased
