为了保护淮北平原的安全,规划要求在淮河正阳关设计洪水位26.37米(黄海高程,下同),蚌埠设计洪水位22.47米时,该河段能安全排洪10000立方米每秒。为此,各行洪区必须有足够的行洪能力。规划中曾研究了口门行洪、漫堤行洪、口门与漫堤相结合的三种行洪方式,规定了相应的口门高程与堤顶高程。并且考虑修建适当的整治工程,如禹山坝退建等,以期满足该段河道的泄洪能
In order to protect the safety of the Huaibei Plain, the planning requirements are that the design flood level of 26.37 meters (Huanghai Elevation) in Zhengyang Pass of Huaihe River and that of Bengbu 22.47 meters in design flood level can safely discharge 10,000 cubic meters per second. To this end, all floodplains must have sufficient flood capacity. Planning has been studied in the mouth gate Hong, flood embankment line, the combination of gate and flood embankment of the three kinds of flood way, provides the corresponding mouth elevation and dike elevation. And consider the construction of appropriate remediation works, such as the Yu Shan dam construction, with a view to meet the flood discharge of the section of the river
