Abstract: The choice of tidal barrage gate is a key technical issue in inlet rebuilt of Maluan bay. This paper compared flap gate driven by bottom shaft with double leaf gate, and emphasized the research on the application of flap gate driven by bottom shaft in construction. As result, double leaf gate was adopted, but the research on flap gate driven by bottom shaft was worth of reference by other projects.

摘要： 马銮湾开口改造工程是马銮湾综合整治开发项目的基础先导工程, 其挡潮闸闸门门型比选是该工程可行性研究的关键技术问题之一。在门型比选过程中, 对双扉门和底轴驱动的翻板闸门进行了重点比选, 并对底轴驱动的翻板闸门是否适用于马銮湾开口改造工程进行了深入全面的研究, 尽管最终结论采用了常规双扉门方案, 但底轴驱动的翻板闸门的适用性研究成果对日后其他工程的选用具有一定的参考价值。
