海底隧道安全监测问题的几点思考

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。

Some Thinking About Safety Monitoring in Undersea Tunneling

Safety monitoring is one of key ensured measure in undersea tunneling.Undersea tunnels have environmental characteristics out of the upland tunnels.Therefore,the safety monitoring of undersea tunneling is complicated and high risks.To solve the issues of safety monitoring of undersea tunneling,based on experience of safety monitoring in upland tunneling and environmental characteristics of undersea tunnel,basic principles and technological essentials of safety monitoring in undersea tunneling are advanced.It includes surveying of lead of seawater permeated,surveying of lead of properties of rock stratum,monitoring of surrounding rock pressure,deformation monitoring,and fixed position monitoring of tunnel.It provides scientific basis for design of safety monitoring way of undersea tunneling.
