摘　　要：研究了水灰比、孔隙率及道路粉尘粒径对透水混凝土强度、透水性、抗堵塞等性能的影响。研究结果表明:随着水灰比的增大,透水混凝土的抗压强度呈先增大后减小的趋势,且孔隙率逐渐减小;随着目标孔隙率的增大,透水混凝土的透水系数逐渐增大,但抗压强度逐渐减小;0.6～1.18 mm范围内的粉尘粒径对透水混凝土的透水性能影响最大,是造成透水混凝土堵塞的主要原因。The effects ofwater cement ratio,porosityand particle size of road dust on the strength,permeabilityand anti-clogging properties of permeable concrete are systematically studied in this paper.The results show that with the increase of the water cement ratio,the measured porosity of the permeable concrete decreases gradually.With the increase of the target porosity,the compressive strength of the permeable concrete decreases gradually,and the permeability coefficient increases gradually.The dust particle size in the range of 0.6~1.18 mm has the greatest influence on the permeability of the permeable concrete,which is the main cause of the blockage of the permeable concrete.
