阜阳城规划颍河西区防洪标准为100年一遇,泉河北区为50年一遇,而泉河阜阳城区段的防洪标准仅为20年一遇,除涝能力为3年一遇的90%,且沿岸近几年已进行大面积高标准滨水园林建设,给城区河道拓宽及堤防加高加宽带来极大的困难,因此如何解决城防标准提高以及泉河除涝达标的问题将成为阜城防洪规划中的关键和疑难问题。笔者根据洪水计算成果分析,多次实地查勘,因地制宜,按照“蓄泄兼筹、分防结合”的原则,提出以相应的解决方案,供参考。
Fuyang City planning Ying River flood control standards for the 100-year event, the spring of Hebei District for a 50-year event, and the Quanhe River in Fuyang City flood control standard is only once in 20 years, the ability to drain floods once every 90 years 90% In recent years, large-area and high-standard waterfront gardens have been built along the coast. This has brought great difficulties to urban river broadening and embankment heightening and widening. Therefore, the issue of how to solve the problems of the improvement of urban defense standards and the achievement of waterlogging standards in Quanhe River will become a Key and difficult problems in urban flood control planning. Based on the analysis of the flood calculation results, the author conducted many field surveys, according to local conditions, in accordance with the principle of “storing and discharging both the reservoir and the reservoir and combining with preventing and preventing”, put forward the corresponding solution for reference.
