北排河挡潮闸除险加固工程设计

针对北排河挡潮闸运行多年接近折旧年限，且该闸所处环境恶劣，常年风蚀、海水侵蚀、冻融破坏，地面沉降、交通桥车辆荷载增大、河道淤积等，工程存在的安全隐患，通过除险加固工程设计，采用新材料进行缺陷处理，使其继续发挥效益。

Design for Tide Gate Reinforcement Project in Beipai River

The tide gate in Beipai River has been operated for many years and is close to depreciation year, where the environment is poor, and also is of perennial wind erosion, marine corrosion, freezing and thawing destroy. Because of ground subsidence, transportation vehicle load increasing, river channel sedimentation, etc,the potential safety danger exists in the project. We try to make it continue to play its benefits through reinforcement project design and using the new material for defect treatment.
