摘要

摘要: 设计了一套适用于富水破碎岩体的注浆加固模拟试验装置。选用PO42.5水泥、SAC42.5水泥和自主研发材料对富水破碎灰岩体进行了注浆加固试验。在分析加固结石体的单轴压缩试验结果的基础上,研究了注浆压力、注浆材料和破碎岩体间泥质充填物对注浆加固效果的影响和作用规律。采用极差分析法确定了影响注浆加固效果的主控因素及各因素间相互作用关系。验证了自主研发材料用于富水破碎岩体注浆加固治理的效果显著优于传统水泥材料。将上述试验结论成功用于指导工程实践,取得了良好的注浆治理效果。

Abstract: An experimental device for testing the grouting reinforcement of water-rich broken rock mass is designed. Grouting reinforcement tests are conducted on the water-rich broken lime rock mass by using cement PO42.5, cement SAC42.5 and self-developed materials. By analyzing on the results of the uniaxial compression tests on reinforced rock samples, the influences of the grouting pressure, grouting materials and argillaceous filler inside the broken rock mass on the grouting effectiveness are studied. ANOVA is adopted to determine the dominant factors which influence the grouting effectiveness and their interior interactions. The self-developed materials are proved to have better performance than Portland and Sulfur-aluminate cement materials. The test results are successfully applied to engineering practice with a good grouting effect.
