大涌浪海域沉箱结构选型方案

随着运输船舶大型化趋势的迅猛发展,与之相适应的大型深水码头逐步向着自然条件更加恶劣的深水区域发展,大涌浪海域的长周期波浪给码头设计施工带来极大的困难。通过某原油码头转换平台的沉箱结构方案选型可见,除进行常规的吃水、压载和浮游稳性验算外,尚应对波浪环境下沉箱的运动响应进行分析。离岸深水海域码头工程的设计施工必须考虑波浪荷载的影响。

Selection of caisson structure scheme under swell condition

Along with the rapid development trend of large-scale ships,port facility towards deep-water is under development,while long-period waves of large swell field will bring great difficulties for the design and construction.Analyzing and comparing the structure schemes for the terminal platform caisson of crude oil terminal,this paper points out that the hydrodynamic response of wave action is necessary in addition to the conventional draft,ballast and floating stability checking.
