上海市苏州河高水位成因分析及对策研究
Cause analysis and countermeasures of rising flood stage in Suzhou River in Shanghai City
摘要
Abstract
In recent years,the stage rising trend of the Suzhou River has been significant,and the flood stage has repeatedly exceeded historical records.In order to analyze the situation and the causes of the flood stage during the Typhoon Muifa in 2022,and explore the countermeasures for the flood stage changes,we use the Mann-Kendall trend test and Spearman trend test to analyze the annual extreme value series of stage,and use the hydrologic model method to invert the flood stage process during the Typhoon Muifa.Under the current engineering situation,the contribution ratio of the two factors both torrential rain and storm surge during the Typhoon Muifa,to the flood stage is about 8∶2.In the future,if the new West Gate of the Suzhou River and the Deep Tunnel project of the Suzhou River participate in project scheduling,the maximum flood stage of the Suzhou River can be reduced by 0.26 m.If the new Huangpu River estuary gate is built,the maximum flood stage of the Suzhou River can be reduced by 0.55 m.These projects can significantly improve the flood and drainage capacity on both sides of the Suzhou River,especially in the central urban of Shanghai city.关键词
