淮河入海水道二期滨海枢纽工程总体布置方案研究

General layout for Binhai Complex of phase-II Huaihe River Sea-entering Channel

滨海枢纽工程为淮河入海水道二期穿越通榆河的立交工程,与通榆河正交。主要任务是将上游洪水及涝水穿越通榆河顺利下泄,维持通榆河的航运、204国道交通,并通过导航工程与永久性通航工程结合,解决入海水道、总渠与通榆河间通航问题。为了保证通榆河不断航及204国道交通顺畅,从工程的技术可行性、经济合理性等方面进行了多方案必较,优选了分建方案中的二期地涵贴近一期地涵总体布置方案,很好地满足了入海水道行洪和通榆河通航的要求。

Binhai Complex of phase-II Huaihe River Sea-entering Channel is interchanged with Tongyu River. The main tasks of the complex compose of discharging of upstream floodwater and waterlogging through Tongyu River, improving navigation condition of Tongyu and traffic of No. 204 National Highway and realizing integrated operation of Huaihe River Channel with main canal and Tongyu River. Alternatives are compared in terms of technical and economic feasibilities, aiming at keeping continuous navigation of Tongyu River and smooth flow of traffic of No. 204 National Highway. General layout of placing underground culvert phase-II next to phase-I are used, which can satisfy the requirement of flood discharge and navigation function of Tongyu River.
