| 摘 要： | 在我国雨水资源缺少地区,把雨水收集起来加以利用成为提高城市道路雨水利用效率的关键.作为雨水收集面的道路,其产流特性对于雨水收集利用起着重要作用.利用人工水泥混凝土处理集雨面进行了道路路面产流特性模拟试验研究.水泥混凝土路面在干燥情况下的临界产流降雨量为1.55 mm,只有降雨量达到或接近1.55 mm,集雨面才会产生径流,次径流系数随着次降雨量增大而增大,产流时间与降雨时间相比存在着明显滞后性,并且径流强度明显小于降雨强度.

| Abstract: | In the area lack of rain water resources,collecting rain water for ut ilization is the key to enhance the utilization efficiency of urban road rainwater.The road runoff charact eristics as water harvesting surface plays an import ant role in the collection and utilizat ion of rainwater.This art icle uses t he art ificial concrete surface to simulate road surface for the research on concrete pavement runoff charact eristics.Threshold rainfall of t he concrete pavement without antecedent rainfall is found to be 1.5 mm.Only if the rainfall amount approaches 1.5 mm,the rain water collection surface will have runoff.Road runoff coefficient increases with the increasing of rainfall amount.Runoff intensity islagging and weak in comparison with rainfall intensity. |
