摘　　要：为研究不同配合比对胶凝砂砾石渗透性能的影响,选取3个因素(粉煤灰掺量、水胶比、砂率),利用响应面法对试验结果进行影响因素的显著性分析,得出胶凝砂砾石渗透系数对单因素和两两因素交互作用的敏感程度。结果表明:粉煤灰、砂率对渗透系数呈现出极强敏感强度,水胶比对渗透系数敏感强度最低;另外因素之间的两两交互作用对渗透性能的影响从高到低依次为水胶比和砂率、粉煤灰和砂率、粉煤灰和水胶比;通过响应面数学模型得出最优配合比为粉煤灰掺量为22 kg/m^(3)、砂率为20%、水胶比为1.0。In order to study the influence of different mix ratios on the permeability performance of cementitious sand and gravel,the mixture of fly ash,water-cement ratio and sand rate were selected,and the test results were analyzed by response surface method to obtain the sensitivity of the cementitious sand and gravel permeability coefficient on single factor and two factors.The results show that the fly ash and sand ratio are extremely sensitive to the permeability coefficient,and the water glue ratio is the lowest.The influence of the permeability is water cement ratio 22 kg/m^(3) and sand rate 20%,water cement ratio 1.0.
