为确定高地下水位地区透水铺装对路面径流的水文控制效果,在上海市区建造了4个实验性透水铺装单元与1个不透水铺装对照,其中3个为设有防水衬底的不透型设施分别为透水混凝土铺装(设施Ⅰ)、水泥稳定碎石基层/缝隙透水砖面层(设施Ⅱ)、碎石基层/缝隙透水砖面层(设施Ⅲ),1个普通缝隙透水砖铺装(设施Ⅳ),以及1个不透水混凝土对照(设施0).历时1年监测了实际降雨条件下4种实验设施的表面径流、排水管出流流量及表面渗透速率,考察不同设施的径流总量削减率、峰值削减及峰现延迟能力.结果表明,缝隙透水砖面层的表面稳定渗透速率明显小于透水混凝土面层,使用1年后,2种面层表面稳定渗透速率均明显下降;4种设施的表面产流均无显著差异;3种不透型设施的就地消纳水量能力均较弱,年径流总量控制率分别为24.2%、28.5%、28.4%,排水管不发生出流的控制降雨量分别为5.2 mm、7.8 mm、7.8 mm;设施Ⅰ的峰值削减与峰现延迟效果弱于设施Ⅱ及设施Ⅲ,且3种设施的峰值削减率和峰现延迟时间与降雨强度呈现显著负相关性. In order to determine the hydrological control effect of water-permeable pavement on surface runoff in high groundwater level, four experimental permeable paving units and one impervious pavement control unit were constructed in downtown Shanghai, three of which are waterproof substrates The impervious facilities were permeable concrete pavement (Facility I), cement stabilized gravel base / gap permeable brick facings (Facility II), gravel base / slotted permeable brick facings (Facility III), and a conventional gap permeable Brick paving (Facility IV), and a water-impermeable concrete control (Facility 0). Surface runoff, discharge flow and surface permeation rates at four experimental facilities under one-year rainfall were monitored over a period of one year, The results show that the seepage rate of the surface of permeable pervious brick is obviously less than that of pervious concrete and the permeation rate of the two kinds of surfacing is obviously higher after one year Decreased; the surface runoff of the four facilities showed no significant difference; the in situ capacity of three kinds of impervious facilities was weaker than the local ones, and the total annual runoff control rates were 24.2%, 28.5% and 28.4%, respectively Outflow does not occur to control rainfall Respectively, 5.2 mm, 7.8 mm and 7.8 mm respectively. The peak reduction and peak delay of facility Ⅰ were weaker than those of facilities Ⅱ and Ⅲ. The peak reduction rate and peak current delay time of three facilities showed a significant negative correlation with rainfall intensity .
