摘　　要：以湖北地区天然碎石为粗骨料,通过试验研究了透水混凝土在不同骨料粒径、水灰比和压实时间情况下的抗压、抗折强度的变化,得到了3个因素对透水混凝土强度影响的基本规律:透水混凝土的强度随骨料粒径的增大呈先升高后降低趋势;透水混凝土的强度随水灰比升高呈先升高后降低的趋势;透水混凝土的强度随压实时间的增加呈上升趋势。By using natural crushed stone as coarse aggregate in Hubei area,the change of compression strength and rupture strength of permeable concrete under different aggregate particle size,water-cement ratio and compaction time was studied by experiment.The basic law of the influence of three factors on the strength of permeable concrete is obtained,with the increasing of aggregate particle size,the strength of permeable concrete increases first and then decreases,with the increasing of water-cement ratio,the strength of permeable concrete increases first and then decreases,with the increasing of compaction time,the strength of permeable concrete increases.
