Safety Analysis of Secondary Lining of Yulinzi Tunnel Based on Field Monitoring

In order to assess the safety of the secondary lining in water-rich Loess Tunnel, this study relies on the Yulinzi Tunnel project to continuously monitor the stress of the steel reinforcement in the secondary lining and analyze the temporal variation of the steel strain. Based on this data, the temp...

520			\|a In order to assess the safety of the secondary lining in water-rich Loess Tunnel, this study relies on the Yulinzi Tunnel project to continuously monitor the stress of the steel reinforcement in the secondary lining and analyze the temporal variation of the steel strain. Based on this data, the temporal variation and distribution characteristics of the internal forces of the structure were obtained through section force calculation. The safety factor of the secondary lining structure was evaluated by calculating the safety factor of the structure. It was found that the variation of the safety factor with time conforms to the exponential function, and the fitting results of different measurement points were good. This could be used to predict the future safety factor of the tunnel and evaluate its long-term safety, which has practical guidance significance for actual engineering projects. In addition, the long-term stress and structural deformation characteristics of the tunnel were obtained through numerical simulation.

abstract	In order to assess the safety of the secondary lining in water-rich Loess Tunnel, this study relies on the Yulinzi Tunnel project to continuously monitor the stress of the steel reinforcement in the secondary lining and analyze the temporal variation of the steel strain. Based on this data, the temporal variation and distribution characteristics of the internal forces of the structure were obtained through section force calculation. The safety factor of the secondary lining structure was evaluated by calculating the safety factor of the structure. It was found that the variation of the safety factor with time conforms to the exponential function, and the fitting results of different measurement points were good. This could be used to predict the future safety factor of the tunnel and evaluate its long-term safety, which has practical guidance significance for actual engineering projects. In addition, the long-term stress and structural deformation characteristics of the tunnel were obtained through numerical simulation.
