水利与水运规范挡潮闸上波浪力的比较计算

Comparative Calculation of Wave Forces on Tidal Gate in Water Conservancy and Port and Waterway Code

在常规的内陆水闸设计中,波浪一般是风成浪,在水闸的稳定计算中不是控制性荷载。随着国内外海洋工程的发展,各种填海造地工程和人工岛礁的建设,挡潮闸面临的自然条件越来越复杂,挡潮闸上的波浪力作用往往成为其设计规模的决定性因素。针对这种情况,文章以某海洋岛礁工程上挡潮闸为例,比较了常见的水利与水运规范中关于水闸上波浪力的相关计算方法。证明了水运行业中波浪力的计算方法更适用于波高较高时的挡潮闸设计,可为类似工程的设计和规范的更新提供有益的参考。

In the conventional design of inland gate,the wave is usually wind-generated wave,which is not the controlling load in the sluice stability calculation.With the development of offshore engineering at home and abroad,the construction of various land reclamation projects and artificial islands and reefs,the natural conditions of tidal sluice are more and more complicated,and the wave force action on the tidal sluice is often the decisive factor of its design scale.In view of this situation,the paper takes the upper tidal sluice of a Marine island and reef project as an example,and compares the calculation methods of wave force on the sluice in common water conservancy and water transportation codes.It is proved that the calculation method of wave force is more suitable for the design of tidal sluice when the wave height is higher in the water transportation industry,which can provide a useful reference for the design of similar projects and the update of the code.
