MODEL TEST ON DEFORMATION MECHANISM OF TUNNEL AT LANDSLIDE SITE

Based on the laboratory geomechanical model test, the interaction mechanism between landslide deformation and tunnels, the variation regularities of the pressure in surrounding rocks and lining,the deformation features of landslides and tunnels are studied. The interaction relationship between landslide deformation and tunnels during sliding plane softening with water and creep occur is emphatically studied. The study result provides a scientific basis for prediction and treatment of the deformed tunnel.
