Abstract The existing theoretical researches on the damage mechanisms of tunnel lining under high-speed train loads，which are generally based on the tensile and compressive characteristics of conventional concrete，seldom consider the tenacity and failure characteristics of fiber concrete，and very limited practice examples of fiber concrete applied to high speed railway are documented in literature. In this paper，a series of fiber concrete experiments with different fiber types，lengths，and volume ratios were conducted to obtain the tensile and compressive characteristics of fiber concrete，and the failure characteristics of different fiber concretes were observed by the DIC technology after the experiments. The concrete damage parameters were determined based upon the equal strain assumption and Najar¢s damage theory，and the effects of the type，length and volume ratio of fiber on the damage development of the tunnel lining under the excitation force caused by trains at different speeds were analyzed by utilizing the finite element method to simulate the rock mass and the tunnel structure. The results indicate that the fiber can effectively improve the damage resistance of concrete. Specifically，the fiber in concrete can alleviate the multi-step damage development under train excitation loads and greatly reduce the final damage of tunnel lining after train loading. When the volume ratio of the fiber with a shorter length is lower than 0.15%，the glass fiber achieves the greatest improvement in the damage resistance of concrete by 69.5% to 74.9%，followed by mixed fiber，and the improvement by the PVA fiber is only 42.6% to 48.8%. However，when the volume ratio is higher than 0.15%，the negative effect resulted from fiber clustering overweighs the positive effect caused by its bridging，resulting in a significant reduction in the peak strength of fiber concrete. The maximum reduction value of the PVA fiber is 94.3%，which makes the damage resistance of the fiber concrete inferior to that of the conventional concrete. In addition，it is observed that the performance enhancement in damage resistance of 6mm fiber is higher than that of 12 mm fiber. The train speed has a great influence on the final damage value of fiber concrete lining，and both the final damage value and the vertical peak displacement increase with increasing the train speed.
