摘要

沈家门港隧道工程为我国大陆首次采用沉管法修建的海底行人交通隧道。为解决海浪、潮汐等对沉管隧道施工的影响问题，通过力学计算分析和管段浮运、沉放方法的选择，施工窗口时间的确定，针对管段浮运、沉放、水力压接、回填等关键问题进行重点分析和阐述。得出：通过合理的施工窗口时间确定、施工方法的选择、具体施工参数的确定、适当的安全系数放大等施工控制技术，能实现海底隧道管段的浮运和沉放。

Abstract

Shenjiamen port subsea tunnel is the first subsea passenger tunnel in mainland China built by immersed tube method. In the paper, the influence of the waves and tides on the construction of the subsea tunnel is presented, proper tube towing method and proper tube sinking method are selected on basis of mechanical calculations and analysis, proper construction window time is determined, and the key points in the towing, sinking, connection and backfilling of the tubes are analyzed. In the end, the tunnel has been completed successfully.

Key words： immersed tube tunnel; towing; sinking; construction control technology
