    摘要:

    为研究海绵改造对城市洪涝的影响,有效提高城市对洪涝问题的韧性,对福州市晋安河片区海绵改造效果进行分析。基于InfoWorks ICM模型对片区管网、地表、河道进行耦合模拟,设计了7种海绵改造方案,对各方案计算结果进行评估,并进一步选择琴亭湖附近典型排水片区,量化分析了海绵城市建设与湖库联合调度协同措施下片区的内涝响应。结果表明:构建的洪涝模拟模型能有效模拟晋安河片区暴雨内涝过程,不同的海绵改造措施对最大淹没面积、溢流节点数、超载管道数以及主河道不同断面水位的影响有所不同;全域海绵改造与管网优化组合的方案作用下,模拟得到的海绵改造综合效益最优。苏迪罗台风降雨驱动下,典型排水片区在无海绵改造措施下的总淹没面积为22.87hm2,采用可持续的城市排水系统(SUDS)措施后,淹没面积减小为22.48hm2,进一步加入调度规则,总淹没面积减小为9.83hm2,仅采用源头海绵改造措施在面对极端降雨时效果有限,结合SUDS与湖库调度可以有效减缓内涝问题。

    Abstract:

    In order to study the influence of sponge reconstruction on urban flooding/waterlogging and effectively improve the resilience of cities to flooding problems, a sponge reconstruction effect analysis was carried out in Jin’an River drainage district of Fuzhou City. Seven sponge reconstruction schemes were designed based on coupled simulation of the district’s pipeline network, ground surface, and rivers with the InfoWorks ICM model, and the calculation results of different schemes were evaluated. Furthermore, with a typical drainage area near Qinting Lake as the object, flooding responses under the cooperative measures of the sponge city construction and joint scheduling of lakes and reservoirs were quantified and analyzed. The results show that the constructed model can effectively simulate the rainstorm waterlogging process in the Jin’an River drainage district, and influences of different sponge reconstruction measures are different on the maximum inundation area, the number of overflow nodes, the number of surcharged pipes, and the water level of different sections of the main river channel; the comprehensive benefit is the best under the combination of the whole-area sponge reconstruction and pipe network optimization. Under the Soudelor typhoon rainfall, the total inundation area of the drainage area without adopting sponge reconstruction measures was 22.87 hm2, which was reduced to 22.48 hm2 after adoption of the sustainable urban drainage system(SUDS), and further to 9.83 hm2 after incorporation of the scheduling rules, demonstrating that the effect of source sponge modification is limited in face of extreme rainfall, and combining SUDS with lake and reservoir scheduling can effectively mitigate flooding problems in the study area.
