This paper represented the numerical analysis of the tunnel lining which was used for maintaining the old tunnel. The tunnel lining was made from FRP corrugated sheet that supported the lining concrete in the tunnel and flowed the water or / and the moisture swept on the tunnel surface. The FRP sheet was supported by the anchor bolts. In numerical analysis, the finite element degenerate shell was adopted to represent the FRP behavior. Firstly, the proposed FRP sheet was adopted and the distribute load equivalent to the concrete peeled from the tunnel lining was applied and the stresses of the FRP sheet, the tensile force of bolts and the deflection of FRP sheet were investigated. Then, secondary, the FRP corrugated sheet with longitudinal cover strip was investigated. From the numerical analysis, the effectiveness of the FRP corrugated sheet was confirmed.
