| 摘 要： | 悬浮隧道直接处于波流作用的自然环境中，结构的动态响应是关注的焦点。本文将悬浮隧道和支撑结构简化为空间梁系有限单元模型，采用梁元的CR描述法，在考虑波流与结构相互作用的条件下，概述了波流作用下悬浮隧道系统的动态响应计算方法。计算分析了波浪入射角、表面流速、隧道断面形式和支撑形式对悬浮隧道动态响应的影响。

| Abstract: | The submerged floating tunnel is situated directly in the natural environment with wave and current,so the dynamic response of the structure should be the focus of attention.In this paper the submerged floating tunnel(SFT) with its supporting system is simplified as a finite element model of a spatial beam system.By employing beam element CR formulation and considering the interaction of the combined wave-current and the structure a calculating method of the dynamic response of the SFT subjected to the combined wave-current is established.The influences of incident angle of wave,surface flow velocity,shape of tunnel's section and support structures on the dynamic response of an SFT are analyzed. |

| Keywords: | submerged floating tunnel dynamic response wave and current geometrically non-linear |
