摘　　要：采用灰色关联分析法,分别利用均值化和初值化对数据进行处理,研究了胶砂比、水胶比以及稳定剂用量等因素与水泥基灌浆料抗压强度、流动性能等的灰色关联度。计算结果表明:水胶比与灌浆料的1 d、3 d及28 d抗压强度的相关性均最高,其次是胶砂比及减水剂掺量;水胶比、胶砂比对灌浆料流动性的影响程度基本相同,且高于其它因素;胶砂比对灌浆料拉伸粘结强度影响最大,水胶比、减水剂掺量对灌浆料拉伸粘结强度的影响程度基本相同。The grey correlation between the factors such as C/S ratio,W/C ratio et al and the performance of cementitious grout such as compressive strength,fluidity et al were studied through grey correlation analysis. The data were processed using initialization and average,respectively. The results show that the correlation between W/C ratio and the 1 d,3 d and 28 d compressive strength of cementitious grout is the highest,followed by the ratio of mortar and the amount of water reducing agent. The influence of C/S ratio and W/C ratio on the fluidity of grouting material is basically the same,and higher than other factors. The effect of C/S ratio on the tensile bond strength of grouting material is the highest. The effect of W/C ratio and water reducing agent on the tensile bond strength of grouting material is basically the same.
