【摘要】 本文以某一实际平台桩柱为例,对其进行波浪作用以及波浪与地震共同作用研究。依据我国海港水文规范JTJ213-98、DNV的环境条件和环境荷载规范以及API的相关规范[1-3],对波浪荷载的计算采取不同的简化处理方式,从而分析流体的附加质量效应和流固耦合效应在不同工况下对桩柱结构响应的影响,并分析了该影响随工作水深和波浪参数的变化规律。结果表明,两种工况下流体的附加质量效应和流固耦合效应对桩柱响应的影响趋势并不相同,当进行波浪与地震共同作用分析时,有必要考虑流体附加质量效应和流固耦合效应对结构响应的影响。更多还原

【Abstract】 In this study,the dynamic responses of the piles with small dimension under the combination of seismic and wave action are investigated.According to the codes of Harbour hydrology(JTJ213-98) and environmental conditions and environmental loads(SY/T10050-2004),and other relative codes,different simplified expressions are adopted to calculate the wave loads and the effect of added mass of sea water and the coupling effect of fluid and structure on the pile responses with different working depths and variable wave parameters.Results show that the effects of added mass of sea water and fluid-structure coupling on the pile responses are different under different working conditions.Considering both effects in the analysis of ocean structure consisting the piles with small dimension under the combination of seismic and wave action is necessary.更多还原
