摘    要:针对上海世博城市最佳实践区北区的不透水景观水塘下渗改造,开展了雨水滞留下渗现场试验研究.改造前的试验表明,雨水下渗速率与雨水塘地下水水位差呈线性关系;在改造后的雨水塘内开展试验,进一步验证了该结论,并确定了动态下渗速率.因此,提高塘内动态水位促进雨水下渗,有助于实现园区17.6 mm雨水径流在3 d内被下渗利用,达到国际绿色社区认证体系(LEED ND)的铂金认证要求.

关 键 词:雨水渗透塘    下渗系数    低影响开发    国际绿色社区体系认证

Abstract:Taking the transformation of an impermeable pond in the north urban best practices area (UBPA) of Shanghai World EXPO as an example, a field infiltration study was conducted. The experiment before the engineering indicated a linear relationship between the infiltration rate and water level gap (i.e., pond water level versus groundwater table), which was further verified by the experiments within the transformed infiltration pond. With the measured dynamic infiltration rate, it is presented that adjusting the pond water level dynamically is a practical approach to enhance runoff infiltration, critical in achieving 17.6 mm UBPA runoff reuse or infiltration within three days, certified by LEED ND platinum grade.
Keywords:rainfall infiltration pond  infiltration coefficient  low impact development  Leadership in Energy and Environmental Design for Neighborhood Development(LEED ND) Certification
