Abstract

To study the relationship between the stability of layered surrounding rock tunnel and the thickness and inclination angle of the layered rock, using the discrete element analysis software UDEC, the deformation and stress characteristics of layered surrounding rock tunnel are analyzed under different inclination angle and thickness conditions after the tunnel excavation. Meanwhile, the influence of different inclination angle and thickness on the stability of layered surrounding rock tunnel is studied. The results show that when the layer thickness and the excavation span are the same, the vertical displacement, horizontal displacement and maximum principal stress of the surrounding rock of the tunnel show a low of increasing first and then decreasing with the increase of the inclination angle of the structural plane. When the inclination angle and excavation span are same, the vertical displacement, horizontal displacement and maximum principal stress of layered surrounding rock of the tunnel gradually decrease with the increase of the layer thickness. When the inclination angle of the structural plane is 30°, the vertical displacement of the surrounding rock of the layered surrounding rock tunnel is the largest; When the inclination angle of the structural plane is 45°, the horizontal displacement of the surrounding rock of the layered surrounding rock tunnel is the largest; When the inclination angle of the structural plane is 45°, the layered surrounding rock tunnel principal stress is the largest.
