摘要
Long undersea tunnels, and particularly those that are built for transportation purposes, are not commonplace infrastructure. Although their planning and construction take a considerable amount of time, they form important fixed links once in operation. The fact that these tunnels are located under the sea gen- erally involves unique challenges including complex issues with construction and operations, which relate to the lack of intermediate access points along the final route of the tunnel. Similar issues are asso- ciated with long under-land tunnels, such as those under mountain ranges such as the Alps. This paper identifies the key issues related to the design and construction of such tunnels, and suggests a potential solution using proven technology from another engineering discipline.
长大海底隧道尤其是运输用长大海底隧道,并非寻常的基础设施工程。尽管长大海底隧道的设计和施工相当耗时,但一旦建成投运,便可形成重要的越海通道。此类隧道建在海底,会面临独特的挑战,包括一系列施工和运营方面的复杂问题。此类挑战与最终隧道路径缺少中间辅助点有关。地下隧道(如穿越阿尔卑斯山之类山脉的隧道)也面临类似问题。本文将探讨长大海底隧道设计和施工方面的关键问题,并采用其他工程专业所用的成熟技术来提出可能性解决方案。
