Abstract：Research purpose: In mountain area, there are a lot of railroad tunnels are built in slope. And some tunnel's diseases, such as deformation and fracture, occur frequently in these tunnels. The survey shows that deformation and fracture of tunnel is correlative with landslide intimately and endangers security of trains running seriously. In view of the problem, this paper studied the deformation features of tunnels, the interrelation between landslide and tunnel deformation, and effective engineering measures to control tunnel deformation.
Research result: Four typical geological mechanics models to analyze interrelation between landslide and tunnel deformation are given. And the mechanical patterns of tunnels situated different place in landslide are analyzed. On the basis of above, the engineering measures to control tunnel deformation at landslide site are studied too. The viewpoint is set forth that engineering measures should be suitable to the deformation features of tunnels, and the specific choosing method is given.
Research conclusion: The relative position between tunnel and sliding plane is the major cause to determine the deformation features of tunnel; the engineering measures should be suitable to the deformation features of tunnels.
