| Abstract: | This paper introduces the design process of the Lanjiayan extra-long highway tunnel with soft rock, analyzes mechanical properties of tunnel lining structure which is simulated with beam-spring model using finite element mentod. The design thought and support means are introduced, the stress of tunnel secondary lining is calculated and structure stability is analyzed to prove the rationality and reliability of support parameters. |
