摘要：

Highway tunnels built in China in the early years of operation have different forms of diseases, which have a great impact and threat to the normal operation and safety of the tunnel. To ensure the safety and stability of the lining structure, this paper analyzes the mechanical behavior of the lining structure under the influence of the disease and reveals the evolution law of the lining crack disease for typical tunnel lining cracks. The results of the study show that only the circumferential and longitudinal stresses at the vault increase when cracks exist in the inner wall of the lining vault. The longitudinal cracks in the inner wall of the lining have the greatest influence on the lining stress state.
