桩基码头前沿顶高程设计方法

Design methods of top elevation of piled wharf

分析和总结国内外规范中桩基码头前沿顶高程的设计方法,分别从设计水位、设计波浪、波峰面高度和气隙高度或富裕高度等方面针对有掩护和开敞式桩基码头的高程设计方法进行研究,总结出有掩护和开敞式桩基码头前沿顶高程的详细设计方法。尤其是针对开敞式码头得出了气隙方法和允许桩基码头上部结构承受波浪力的两种设计方法,并通过气隙高度和超越概率的相关试验得出气隙高度设计方法,针对允许桩基码头上部结构承受波浪力的情况给出了主要面板下表面设计在最大波峰面以上和所有的管架等在最大波峰面以上两种设计方法。

We analyzed and summarized the design methods of top elevation of piled wharf in domestic and foreign specifications,studied the design methods of elevation for protected and unprotected piled wharfs from the aspects of design water level,design wave,wave crest height and air gap or safety height,etc.,summarized the detailed design methods of top elevation of protected and unprotected piled wharfs.Especially for the unprotected wharf,both of design methods of air gas and superstructure bearing the wave loads are given and the design method of air gap is gotten by the test results of the air gap and it's exceeding probability.As for the superstructure is designed to bear the wave loads,two situation of the underside of slab above the wave crest and pipe rack above the wave crest are introduced.
