摘　　要：“渗”是海绵城市建设六字方针之首,增强下垫面的自然渗透能力是海绵城市的重要举措。为研究不同护坡材料对地表径流的渗透性能,在现浇绿化混凝土、生态砌块、格宾石笼、植物蜂巢等4种生态护坡材料上开展了径流模拟试验,采用下边界开始溢流时间、径流入渗率、入渗水量比例、平均汇流速度等指标分析评价这4种生态护坡材料对径流的延滞效应。结果表明:本次试验选取的4种生态护坡材料径流入渗性能显著优于普通植草护坡,符合海绵城市关于加强雨水渗透、滞留的有关要求,建议在海绵城市建设中加以推广应用。试验所获得的参数,可以为海绵城市建设评估、河道生态修复工程的材料选择提供参考。“Infiltration”is the first of the six-word policy of sponge city construction,and it is an important measure to enhance the natural infiltration ability of the underlying surface.In order to study the different ecological slope revetment materials on runoff infiltration,four kinds of materials were carried out,such as green concrete in situ,ecological greening block,gabion stone cage,and plant hives,so on four different ecological slope protection material simulation test was carried out by runoff,by carrying out runoff simulation test,analysis of the lower boundary began to overflow time,runoff infiltration rate,infiltration water proportion,and average flow velocity,and evaluation the effect of four kinds of materials on runoff.The results showed that the runoff infiltration performance of the four ecological slope protection materials selected in this experiment was significantly better than ordinary grass protection materials,which obviously meets the relevant requirements of strengthening rainwater infiltration and retention in sponge cities,and it is suggested to be popularized and applied in the construction of sponge cities.The parameters obtained from the experiment can provide reference for the evaluation of sponge city construction and material selection of river ecological restoration project.
