To investigate the mechanical responses of secondary lining of high-speed railway tunnel, two numerical models for simulatingReinforced Concrete Secondary Lining (RCSL) and Plain Concrete Secondary Lining (PCSL) are built respectively based on theprinciple of soil-structure interaction. The simulations are performed under different values of coefficient of lateral pressure (λ). Thenumerical results indicate that the embedded reinforcement enhances the strength of secondary lining. The coefficient of lateralpressure has significant influence on the secondary lining strength.
