The concrete lining layer of the tunnel is highly susceptible to erosion ions under the interaction of fluid and structure,leading to performance degradation.In order to analyze the degradation effect of erosion ions on the lining layer of Zhoupangou Tunnel under fluid solid coupling,the degradation calculation formulas of reinforced concrete in different corrosive media were investigated.Then,FLAC3D was used to numerically simulate the impact of erosion ions on the lining layer under fluid solid coupling in Zhoupangou Tunnel.Finally,the estimated service life of Zhoupangou Tunnel was calculated through the formulas.Intended to provide reference for the maintenance of lining concrete during the operation period of Zhoupangou Tunnel.
