摘　　要：骨料级配特征对透水混凝土配合比优化设计方法及其基本性能有较大影响.采用A,B,C3种粒径的骨料进行混料设计试验,通过对大量的试验数据拟合与方差分析,建立了透水混凝土有效孔隙率、单位体积骨料颗粒数量、骨料比表面积、不同龄期抗压强度与骨料级配的关系式.研究结果对透水混凝土配合比设计方法优化和基本性能的预测具有重要的指导意义.Aggregate gradation characteristics has great influence on the optimization of mix proportion de sign and the basic performance of pervious concrete. Three kinds of aggregates with different particle sizes of A, B and C were used for mixture design test. By large number of experiment data fitting and variance analysis, the correlations between the pervious concrete valid porosity, unit volume aggregate particle number, aggregate specific surface area, compressive strength and aggregate gradation were established. The result is of great significance for the optimization of mix proportion design of pervious concrete and the prediction of basic performance.
