Abstract
In order to reveal the deformation law of tunnel structure under different spatial positions of landslide tunnel system, the rock deformation around tunnel under 12 working conditions was compared and analyzed by numerical simulation method. The results show that the vertical displacement distribution of rock around the tunnel at different locations is determined by the upper and lower regions of the sliding zone, and the settlement around the tunnel is greater than that of the tunnel under the sliding zone. The settlement decreases with the increase of the distance from the slip zone. The analysis results can provide reference for the design and construction of tunnel site selection.
