摘　　要：运用灰色系统理论研究了水灰比、集灰比与集料级配等因素对混凝土透水砖表观密度、有效孔隙率、透水系数和抗压强度的影响。结果显示:各因素对混凝土透水砖表观密度和抗压强度的影响规律一致:集灰比>水灰比>集料级配>0.6;各因素对混凝土透水砖有效孔隙率和透水系数的影响规律一致:集料级配>集灰比>水灰比>0.6;研究结果对混凝土透水砖配合比设计具有指导作用。The influence factors on the apparent density, effective porosity, permeable coefficient and compressive strength of concrete permeable brick were studied using the grey system theory, such as the mass ratio of water to cement, mass ratio of aggregate to cement and aggregate gradation. The results show that the influence law is agreement between factors and the apparent density and compressive strength of concrete permeable brick： mass ratio of aggregate to cement 〉 mass ratio of water to cement 〉 aggregate gradation 〉 0.6 ; the influence law is agreement be and permeable coefficient of concrete, permeable brick： aggregate tween factors and the effective porosity gradation 〉 mass ratio of aggregate to cement 〉 mass ratio of water to cement 〉 0.6; The research results play a guiding role on the mix design of concrete permeable brick.
