| 摘 要： | 对开孔铺面的土柱入渗试验结果是：在充分供水条件下，下渗强度和下渗量的大小与土壤性质、土壤含水量及淹水深度有关，利用试验结果对典型城市设计暴雨分析表明，开孔铺面对地表径流确有削减作用，但不同的土壤性质、土壤含水量，降雨强度、降雨历时的削减作用有显著的判别。

| Abstract: | The results of stormwater infiltration test of soil column with perforated pavement expressing the infiltration intensity and capacity are affected by soil characteristics, soil moisture and water depth on the pavement. The analysis of design storm on typical cities indicates that perforated pavement reduces the surface flow rate of stormwater and the ratio of reduction depends on soil characteristics, soil moisture,and storm intensity and duration. |

| Keywords: | soil column infiltration test surface flow coefficient perforated pavement |
