中文摘要：

为了明确悬浮隧道在水下环境及交通荷载作用下的受力行为,以及承受冲击、地震等极端荷载时亟待研究解决的动力问题,首先综述了波流环境中悬浮隧道管体、锚索构件动力响应、振动稳定性分析与锚索疲劳损伤评估等方面的研究进展,对比了几种锚索振动理论分析模型的差异;同时针对悬浮隧道在运营中可能面临的地震、极端波浪等偶然作用威胁,总结归纳了该方面结构振动研究的最新进展。分析结果表明：现有的动力分析理论模型基本采用将隧道管体、锚索分开讨论或者对两者耦合振动系统简化处理的方法,而对考虑车辆移动荷载作为外部激励时相互耦合的动力研究几乎未见,因此有必要在流体-悬浮隧道-车辆系统耦合振动方面展开研究;由于地震、冲击荷载等偶然作用导致结构振动的计算模型不够精确及缺乏试验数据,有必要建立多种特殊荷载和灾害作用下的多尺度动力响应理论模型并开展试验研究。

英文摘要：

In order to figure out mechanical behaviors of submerged floating tunnel（SFT）under underwater environment and traffic loads,and solve dynamic problems needed to be researched and solved due to extreme loads such as impact and earthquake,the research developments regarding dynamic response and vibration stability of SFT tube and anchor-cables were reviewed.Method for fatigue damage assessment of anchor-cable was introduced.Differences of several kinds of anchor-cable vibration theory analysis models for SFT were compared.Aiming at the possibility bearing of the threats of accident situations,such as seismic excitation,extreme wave load during SFT service,recent vibration research achievements under these situations were summarized.The results show that the tube and cable of SFT are usually separately discussed or the coupled tube-cable vibration system is simplified in present dynamic analysis theory models,while the coupled dynamic behavior research of SFT with consideration of the vehicle load acted on it as an external excitation is almost blank.So it is necessary to investigate the coupled vibration of fluid-SFT-vehicle system.At the same time,aiming at the problems of lacking accuracy and test data in the vibration calculation model resulting from accident situation including dynamic analysis of earthquake,impact load,it is necessary to establish the multi-scaledynamic response theory model of SFT under the action of multi-special loads and disasters and the corresponding experimental researches should be conducted.
