摘　　要：以C20透水混凝土为设计基准,再生骨料和橡胶颗粒掺量为影响因素,通过测定透水混凝土的连通孔隙率、透水系数、28 d抗压强度、劈裂抗拉强度及弹性模量等性能指标,研究再生骨料和橡胶颗粒对透水混凝土基本性能的影响规律;同时,采用拟合回归和综合对比的方法建立透水混凝土连通孔隙率与透水系数、劈裂抗拉强度及弹性模量与28 d抗压强度之间的关系模型。Based on the influence factors of recycled aggregates and rubber particles on the basic properties of C20 pervious concrete, and then studied the influence made by recycled aggregates and rubber particles by measuring the porosity, permeability coefficient, compressive strength at 28 d, tensile splitting strength, elastic modulus of pervious concrete. Meanwhile, the test established the relationship model between the porosity and permeability coefficient, tensile splitting strength and compressive strength at 28 d, elastic modulus and compressive strength at 28 d using the fitting regression and comprehensive comparative method.
