| 中文摘要 |
| 为考察缝隙透水砖铺装的基层构造与材料对设施运行效果的影响，在上海市区建造了2个缝隙透水砖铺装（permeable interlocking concrete pavement，PICP）与1个不透水混凝土铺装（concrete pavement，CP）停车场，其中2个缝隙透水砖铺装分别采用水泥稳定碎石（PICP1）和普通碎石（PICP2）作为基层结构.在2018年实际降雨条件下对2个设施的水文效果及底部出流水质进行了长期监测.结果表明PICP1与PICP2的年径流总量控制率相近，分别为37.0%和38.7%，PICP1的峰值削减率及峰现延迟时间略优于PICP2.水质控制效果方面，PICP1比PICP2有更好地NH4+-N转化效果，两种设施底部出流均存在NO3--N淋出的现象；PICP1底部出流的TSS、TP、颗粒态磷和溶解态磷浓度均低于PICP2.采用水泥稳定碎石作为基层有助于提高设施的水质净化效果，并改善设施的水文控制效果. |
| 英文摘要 |
| Two permeable parking lots and one impervious concrete pavement were constructed in Shanghai to study the hydrological and water quality performance of permeable interlocking concrete pavements (PICP) with different base course materials. The hydrological performance and water quality of the influent and effluent under actual precipitation conditions in 2018 were monitored, and the two PICPs used cement-stabilized crushed stones (PICP1) and crushed stones (PICP2) as the base course, respectively. Results show that the annual total volume reduction rates of PICP1 and PICP2 are 37.0% and 38.7%, respectively. The peak flow reduction rate and the time to the peak flow of PICP1 are slightly better than PICP2. PICP1 has better transformation efficiency on NH4+-N in comparison to PICP2, and the release of NO3--N occurs in both PICPs. Moreover, PICP1 has lower effluent concentrations than PICP2 on pollutants like TSS, TP, PP, and DP. The PICP with cement-stabilized crushed stones as base course is helpful to improve the hydrological performance and water quality of the effluent. |
