国内外拟建水中悬浮隧道设计方案研究

Design Schemes of Domestic and Overseas Submerged Floating Tunnels

随着离岸工程技术的发展,以及对跨水域交通需求的增加,水中悬浮隧道以其独特的优势受到关注。为了进一步认识和了解这一创新型水下交通结构,结合近年来国内外出现的拟建悬浮隧道设计方案,对其中涉及到的断面形式、支撑系统、结构连接、结构材料、作用荷载等基本方面进行分类概述,最后提出相关建议及展望。对国内外悬浮隧道设计方案的综述,希望能为今后悬浮隧道的研究、设计提供借鉴和参考。

With the development of offshore engineering technology,as well as the increased demand for waterway crossing transportation,submerged floating tunnel（ SFT） which has distinctive advantages compare to other waterway crossing solutions attracts more and more attentions. In order to better understand this innovative underwater transportation structure,this paper analyzed the design schemes of domestic and overseas SFT in recent years by considering fundamental aspects such as cross-section,support system,structural connection,structural material,imposed load etc. Several suggestions were proposed which can provide references for future researches and designs of SFT.
