苏州河河口水闸历史、现状及未来

The History,Present and Future of the Suzhou Creek Sluice-gate in Shanghai

苏州河是上海标志性河流,其河口更是上海的发源地与世界关注的焦点。基于苏州河历史演变及河口变迁情况分析,阐述了不同时期各方面对苏州河河口水闸的要求和水闸发挥的作用,以及历史和现状情况下水闸闸址位置、工程规模、结构形式、运行方式。根据现状河口水闸运行情况,分析了水闸存在的主要问题,并提出了完善措施建议,包括:淤积监测与定期清淤、防撞风险研究、大修方案研究等。最后,根据未来城市总体规划、防洪要求、水资源调度和水环境整治要求,以及黄浦江河口建闸等相关工程规划情况,预测了未来苏州河河口水闸的功能和运行方式,从而为相关部门提供决策参考。

Suzhou Creek is an iconic river of Shanghai. For often affected by storm surge disaster, tidal barriers had been constructed at its estuary for many times in history. Based on analysis of the historical evolution of the Suzhou Creek and its estuary, the locations, sizes, structures, operation modes of history and current barriers at the estuary are represented, and requirements from various to the barriers and roles of every barrier during different periods are also analyzed. According to the operation status of the current Suzhou Creek barrier, the paper analyzes the main problems of it, and proposes measures to improve recommendations, including monitoring silt and periodic desihation, research risk of ship collision, research overhaul plan for the barrier. Finally, based on the future of urban planning, flood control, water resources and water environment improvement scheduling requirements, and the Huangpu River storm barrier and other related project planning, the future of Suzhou Creek barrier function and operation mode are predicted, so as to provide the relevant departments decision-making.
