海底隧道混凝土结构耐久性监测
Durability Monitoring of Concrete Structure of Subsea Tunnel
摘要
Abstract
Subsea tunnel at Jiaozhou bay is the second self-built tunnel in China with the designed service life for over 100 years.The anode-ladder-system is selected and used to monitor the chloride ion penetration into reinforced concrete structures in a corrosion groundwater and saline-fog environment.The expansion-ring-system is used to monitor the water transportation in lining concrete.And the durability of concrete structure of subsea tunnel is assessment according to the monitoring data.The anode-ladder-system monitor sensors are embedded into shotcrete and lining concrete in the Level Ⅵ broken surrounding rock zones of sea section and in the entrance of subsea tunnel.The expansion-ring-system are installed into lining concrete in the deepest section with Level Ⅵ broken surrounding rock zone and the entrance of subsea tunnel.The measurements from sensors installed in concrete structure for 1 year are promissory and follow the expected trends.According to the monitor results,the durability of concrete structure is good.关键词
