摘　　要：基于流体-结构相互作用理论,采用有限元方法对海洋储油罐平台的地震反应进行了分析。首先,将基于流固耦合理论的耦合模型计算结果同基于Housner理论的简化模型计算结果进行了比较,明确了采用耦合模型的必要性。然后,分析了储油罐内液体深度、地震波输入方向、地震波维数、地震波波型等因素对储油罐平台和罐体反应的影响。得出的结论可为海洋储油罐平台的设计提供参考。Finite element method based on the theory of interaction between fluid and structure was used to analyze the dynamic response of the offshore jacket platform with oil storage tank during earthquake.Meanwhile,a simplified model based on the theory of Housner was established for the offshore platform as well.The interaction model was more reasonable and credible compared with the above two models.Many factors such as oil depth in the tank,excitation direction,excitation dimensions and earthquake wave type were studied on the interaction model.Several conclusions which could be refered for the offshore platform design were drawn.
