摘要
曹娥江大闸是在强涌潮河口地区建设的大闸。本文分析了挡潮泄洪闸工作闸门的鱼腹式双拱承力体系、扁平大跨度体型、泥沙淤塞及启闭平衡性等特性,从潮位、水压力、潮头、潮速及潮流方向的角度介绍了钱塘江涌潮对于闸门的荷载特征,阐明了闸门的运行对策。这对大跨度特型闸门在强涌潮河口的运行管理具有重要的指导意义。
Caoe River Sluice is located at an estuarial area with strong tidal bore ; for which the characteristics of the fish-bellied and double-arched bearing system, flat structure with large spans, sediment deposition, open and close balance, etc. of the working gates for the tide-water release sluice are analyzed herein, and then the tactic for the operation of the gate is illustrated with the introduction made on the feature of the load from the tidal bore of Qiantangjiang River from the aspects of tidal level, wa- ter pressure, tidal head, tidal velocity and the direction of tidal current. This has an important guiding significance for the operation management of the special-shaped sluice with large spans located at the estuary under strong tidal bore.
