Abstract: This paper is based on the research on the cracking control of the tunnel secondary lining of Wu-Guang passenger dedicated line (Wu-Guang PDL) during service period and provides a new method for evaluating the concrete cracking performance of the tunnel secondary lining during service period. Firstly, research and modeling of the load-bearing mechanism of tunnel secondary lining are made. Then the secondary lining concrete permeability under cyclic loading is tested and the crack extension of the micro crack in concrete of tunnel secondary lining is shown by air permeability coefficient. The test shows that cellulose fibers can improve the anti-cracking performance of tunnel secondary lining concrete during service period.
