中文摘要：

长期以来，如何快速跨越广袤的水域一直是世人关注的焦点。在最近几十年里，一种新的跨越海峡、大江、湖泊、水道的交通结构物水下悬浮隧道吸引了世人的目光。水下悬浮隧道的研究历史虽然短暂，但由于该种结构的新颖性与其独有的优越性与应用潜力，使得世界各国的学者专家为此进行了很多有价值的工作。首先概述水下悬浮隧道的概念、优点及需要研究和解决的关键问题；随后从水下悬浮隧道的隧道管体结构、隧道锚固系统、作用荷载以及锚固基础等几个方面的结构简化模型综述了水下悬浮隧道结构分析的研究现状；最后对水下悬浮隧道的发展方向进行了总结和分析。

英文摘要：

The problem of how to cross a wide water area quickly has been focused on by people for long. In the last few decades, an innovative strucure concept for crossing straits, rivers, lakes and waterways, called Submerged Floating Tunnel, attracts worldwide attention. Though the study history of Submerged Floating Tunnel is short, scholars and experts all over the world have done many valuable jobs on Submerged Floating Tunnel because of its unique novelty, suporiority and application potential. The paper firstly summarizes the concept, virtue and key problems that need to be solved of Submerged Floating Tunnel, then presents the state-of-art of the structural analysis of Submeged Floating Tunnel from several aspects such as tube, anchor system, load and fonndation, and finally sums up and analyzes the development direction of Submerged Floating Tunnel.
