摘要

我国修建的公路隧道在运营初期就有不同形式的病害，对隧道的正常运营和安全造成了极大的影响和威胁。为了保证衬砌结构的安全稳定，本文分析了衬砌结构在病害影响下的力学行为，揭示了典型隧道衬砌裂缝的衬砌裂缝病害演化规律。研究结果表明，当衬砌拱顶内壁出现裂缝时，只有拱顶处的周向应力和纵向应力增加。衬砌内壁的纵向裂缝对衬砌应力状态的影响最大。

Mechanical behavior of a highway tunnel under the influence of lining crack disease

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.
