摘要
通过室内模型注浆试验,研究水泥-粉煤灰-黏土复合浆材扩散半径与注浆后结石体单轴饱和抗压强度受注浆压力、浆液水灰比、注浆时间等单因素和多因素耦合影响规律及其之间的数学模型.试验结果表明:对浆液的扩散半径影响显著性的顺序依次为注浆压力、浆液水灰比与注浆时间;对注浆后结石体抗压强度影响显著性的顺序依次为浆液水灰比、注浆压力与注浆时间,其中水灰比为负向影响。
Based on indoor grouting simulation test, the influence of single and multiple factors of grouting pressure, water cement ratio, grouting time on diffusion radius, cement strength and their correlation were studied. The results show that on grout diffusion radius of influence was significant in the order of grouting pressure, water cement ratio, and grouting time; while on Cement strength of grouted gravels of influence was signi fie ant in the order of water cement ratio, grouting pressure, and grouting time, wherein water cement ratio was negative influence.
