摘要
以琼州海峡大桥为研究对象,根据Morison方程,分别运用Airy线性波、Stokes二阶波和Stokes五阶波进行了数值造波,分析了三种波浪理论模拟的波面升高以及波浪荷载特点,在此基础上将计算的波浪力时程作用于桥塔有限元模型,研究了施工期桥塔的动力响应特点。
Taking the Qiongzhou Strait Bridge as the research object, according to the Morison equation, respectively using the A iry linear wave,stokes second order wave, Stokes fifth order wave made numerical wave m aker, analyzed the wave elevation and wave load characteristics of threekinds of wave theory sim ulations, based on this made the calculation wave processes in bridge tower finite element m odel, researched the dynamicresponse characteristics of bridge tower during construction stage.
