description Due to the complexity of the portal section of high slope tunnel, unsafe accidents are prone to occur. Because of its convenience and accuracy, numerical simulation method is often used in tunnel stability analysis. In this paper, the excavation process of the slope and tunnel at the entrance of the tunnel is simulated by using the finite element software MIDAS-GTS, taking the No.6 tunnel project of the Kovi-Agvida E60 Highway Line in Georgia as an example. According to the results of numerical calculation, although the excavation volume of the slope is large, the displacement is small and the stability is good; the deformation of the surrounding rock of the tunnel is stable, and the displacement of the supporting structure is small, and the maximum displacement is about 20 mm, which is located at the vault. Therefore, the monitoring work should be done well and the support can be strengthened properly during the construction.
