安全监测是海底隧道施工的重要保障措施之一。由于海底隧道具有与陆地隧道不同的环境特点,因此,也就带来了海底隧道安全监测的复杂性与高风险。为了切实解决海底隧道的安全监测问题,结合陆地隧道安全监测经验和海底隧道的环境特点,提出了海底隧道安全监测的基本原则和技术方法,包括海水渗透超前探测、岩层岩性超前探测、围压监测、隧道形变监测、隧道空间位置导向与定位监测等,为海底隧道安全监测方法设计提供了有益的基础依据。
Safety monitoring is one of the important safeguards for the construction of subsea tunnels. Because undersea tunnels have different environmental characteristics than terrestrial tunnels, the complexity and high risk of subsea tunnel safety monitoring are brought about. In order to effectively solve the problem of safety monitoring of subsea tunnels, combined with the experience of terrestrial tunnel safety monitoring and the environmental characteristics of subsea tunnels, the basic principles and technical methods of subsea tunnel safety monitoring are proposed, including advanced detection of seawater infiltration, advanced detection of rock lithology, Monitoring, tunnel deformation monitoring, tunnel spatial location guidance and positioning monitoring, which provide a useful basis for the design of subsea tunnel safety monitoring methods.
