摘　　要：针对功能梯度混凝土在地下工程中的应用问题,研究了多因素(水胶比、粉煤灰、硅粉、聚丙烯酸酯乳液)作用对聚合物水泥基混凝土电通量的影响,确定了各因素对其电通量变化的影响程度,并加以定量化表征;建立了电通量关于各因素的偏最小二乘二次多项式回归分析模型。结果表明:各因素对电通量的影响程度为水胶比>聚丙烯酸酯乳液>硅粉>粉煤灰;当水胶比、粉煤灰、硅粉、聚丙烯酸酯乳液分别为0.22、25%、5%、6%时,电通量最小值为331.5 C。In order to study the application of functionally gradient concrete in underground engineering, the influence of multiple factors (such as water binder ratio, fly ash, silica powder and polyacrylate emulsion) on the electric flux of polymer cement-based concrete (PCC) is studied, and the influence degrees of each factor on the electric flux of PCC are determined, and the quantitative characterization is made. A partial least squares quadratic polynomial regression analysis model is constructed. The results show that the influence of each factor on the electric flux of PCC is water binder ratio>polyacrylate emulsion>silica powder>fly ash;When water binder ratio, fly ash, silica powder, and polyacrylate emulsion is 0.22, 25%, 5% and 6%, respectively, the electric flux of PCC has the optimal value of 331.5 C.
