摘　　要：针对地下有构筑物的城市小区绿地在排水方面面临的问题,研究了在绿地的土壤层中铺设渗透材料(渗透管材、渗透片材)收集下渗雨水的方法,同时考察了采用不同渗透材料铺设方式时的雨水收集、积水消退效果。试验结果表明,使用渗透管材、渗透片材等渗透材料可以对绿地的下渗雨水起到较好的收集利用效果,其中使用渗透管材和间隔铺设方式对下渗雨水的收集效果最好。To solve the drainage problem in green spaces above underground structures in urban residential areas, methods of laying infiltration materials （ tubes, pipes and sheets） in soil layer to har- vest the rainwater were studied. The rainwater harvesting efficiency and standing water elimination effi- ciency were investigated. The experimental results showed that infiltrated rainwater into green space was well harvested by laying infiltration materials such as tubes, pipes and sheets in soil layer. The best harvesting efficiency of infiltrated rainwater was laying infiltration tubes or pipes at specified intervals.
