In order to reveal the internal force law of tunnel structure on different positions of landslide tunnel system, the internal force of supporting structure around tunnel on 12 working conditions was compared by numerical simulation method. The results show that the axial force is much greater than the bending moment and shear force. The influence of buried depth on axial force is greater than that of sliding zone. The bending moment and shear force are lower in the whole range of the arch, while the middle and lower parts of the side wall and the two ends of the invert vary greatly. In the design of similar tunnel structure, axial force should be taken as the main control parameter.
