This paper represents the numerical analysis of the tunnel lining which was used for maintaining the old tunnel. An old tunnel covered with concrete is prone to deteriorate due to an aging effect and water penetration. In the rehabilitation of lining concrete, a steel plate and FRP (Fiber Reinforced Plastics) or carbon sheet have been applied. However, these sheets show small flexural rigidity and do not allow the penetrating water to flow out. In this paper, FRP corrugate sheet was proposed. The tunnel lining was made from FRP corrugate sheet that supported the concrete lining in the tunnel, allowing the water to flow and sweeping the moisture to the tunnel surface. The FRP corrugate sheet was supported by the anchor bolts. In numerical analyses, the finite element degenerate shell was adopted to represent the FRP sheet behavior. From the numerical analysis, the effectiveness of the FRP corrugate sheet was confirmed.
