摘要
Aiming at the problems that the life evaluation results of most lining segments are too conservative and the tunnel life prediction is inaccurate, the existing monitoring data is used to complete the dynamic update of the service life of the lining segments. The results show that in the environment of chloride ion erosion, the theoretical calculation and simulation calculation show that the lining segment will reach the end of life due to insufficient reliability in the 92nd year; using the existing observation data, the theoretical data is dynamically updated according to the Bayesian formula, 88. In the early years, the reliability of the lining segments failed. Tunnel lifespan reduced by 4%. In practical applications, it is necessary to strengthen the protection in advance to ensure that the tunnel can complete the set construction period.
