悬浮隧道(水下连续梁桥)跨越海峡方案研究

在对国内外跨海方案分析的基础上,以国外某海峡通道建设为背景,设计了一种隧道跨海方案——悬浮隧道（水下连续梁桥）,其基础为普通桩柱式桥墩,主梁为隧道行车孔,整个隧道结构体系相对简单,与普通连续梁桥相似。因此,在介绍该方案的特点和技术难点的同时,也对其可行性进行了探讨。

Research on the Scheme of Submerged Floating Tunnel (Underwater Continuous Girder Bridge) Crossing the Strait

Based on the construction of a strait tunnel abroad, a scheme for tunnel crossing the strait-submerged floating tunnel (underwater continuous girder bridge) is designed by analyzing the schemes for crossing the strait both at home and abroad. Its foundation is common pile column pier and girder is driving hole of tunnel. The overall tunnel has a relatively simple structural system and is similar with the common continuous girder bridge. Therefore, its feasibility is also discussed while introducing the features and technical difficulties of this scheme.
