摘要
随着沉管隧道技术的成熟和建设经验的不断积累,国内已运营和在建的沉管隧道达十余座。干坞设计是沉管隧道设计的重点和难点。不同的干坞类型适用于不同的工程条件。该文系统总结了轴线干坞、独立干坞和移动干坞的优越性及局限性,介绍了国内部分已运营和在建沉管隧道的干坞设计经验。
With the technological maturity of immerged tunnel and the continuous accumulation of construction experience,there are more than ten immerged tunnels under the service and construction in China.The design of dry dock is the key and the difficulty in the design of immerged tunnel.The different types of dry dock are suitable for the different engineering conditions.The article systematically sums up the superiorities and the limitations of the axes dry dock,independent dry dock and movable dry dock,and introduces the design experience of dry docks for some immerged tunnels under the operation and construction in China.
