摘要
近年来,校园内涝问题日益突出,以河北水利电力学院为研究对象,基于SWMM模型分析了灰色设施蓄水池以及绿色屋顶、透水路面等6种LID设施的雨洪控制性能。在此基础上,通过设施的组合设计,构建了由径流总量削减率、洪峰流量削减率、延缓峰现时间、全生命周期成本组成的评价指标体系,并利用TOPSIS主观赋权法和熵权法评价了组合方案的综合性能。研究发现,单一设施雨洪控制性能排序为透水铺装>蓄水池>透水路面>下凹式绿地>雨水花园>雨水桶>绿色屋顶。灰绿耦合设施方案5即蓄水池、下凹式绿地、雨水桶的组合方案相对贴近度最高,在雨洪控制和成本控制方面均表现出优异的性能,为最佳方案。
In recent years,the problem of campus waterlogging has become increasingly prominent.Taking Hebei University of Water Resources and Electric Power as the research object,based on the SWMM model,the stormwater control performance of six low-impact development facilities,such as grey facility reservoir,green roof and permeable pavement,was analyzed.On this basis,through the combination design of facilities,an evaluation index system consisting of total runoff reduction rate,peak flow reduction rate,delayed peak time and full life cycle cost was constructed,and TOPSIS subjective weighting method and entropy weight method were used to evaluate the comprehensive performance of the combination scheme.It is found that the order of stormwater control performance of single facility is permeable pavement>reservoir>permeable pavement>sunken green space>rainwater garden>rainwater bucket>green roof.The fifth scheme of grey-green coupling facilities,that is,the combination scheme of reservoir,concave green space and rain bucket,has the highest relative closeness,and shows excellent performance in stormwater control and cost control,
