Abstract

Shanxi loess tunnel has the characteristics which are numerous and complex geological. This paper simulated the construction process of loess tunnel by the finite difference software FLAC3D, analyzed the influence on the tunnel roof longitudinal settlement and horizontal ground surface settlement by different elastic modulus, cohesion, friction angle, Poisson's ratio, excavation step. Gave empirical formula that tunnel uneven settlement of maximum gradient and maximum surface settlement with them under the various influence factors and various factors to the sensitivity level of tunnel construction deformation which are elastic modulus cohesion friction angle. The results provide guidance for the tunnel design.
