波高取值对斜坡堤胸墙结构设计影响的探讨

Influence of Wave Height Value on Mound Breakwater Crown Wall Structural Design

斜坡堤堤顶设胸墙是常用的防浪结构型式 ,在已建的工程中胸墙顶高程一般定在不低于设计高水位以上 1 0倍设计波高处 ,而交通部 1998年发布的《防波堤设计与施工规范》JTJ2 98- 98对于设计波高值注释的不明确给设计带来一定的困惑。本文通过波浪断面模型试验结果 ,分析波高取值对胸墙结构设计的影响 。

Mound breakwater crown wall is a commonly used wave protection structure. In the works already built, the top elevations of crown walls were generally not lower than 1.0 time of design wave height over design high water level. But the 'Codes for Design and Construction of Breakwater' JTJ298-98 issued by the Ministry of Communications in 1998 did not give a definite explanation of the design wave height value and thus brough certain puzzels for design. In this paper, based on wave cross-sectional model experiment result, the influence of wave height value on crown wall structural design was analyzed and suggestions on relevant calculation parameters were put forward.
