摘要
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. © 2016, Editorial Office of Chinese Journal of Geotechnical Engineering. All right reserved.
