This study investigated the impact of aircraft take-off on the surface subsidence during the construction of an airport tunnel project with the numerical simulation. The change rule of surface subsidence of single-track tunnel and double-track tunnel caused by the aircraft position under plane load was analyzed through MIDAS GTS NX software. The results demonstrated that, the surface subsidence in a single-track tunnel moved from the left side to the middle of the right side when an aircraft glided from left to right and the maximum value of surface subsidence continued to increase. In the double-track tunnel, the maximum surface subsidence gradually transferred from the top of the first tunnel to the top of the followed tunnel. When the aircraft load was positioned above the arch shoulder of the tunnel behind and passed through the middle of two tunnels, the maximum surface settlement value exceeded 30 mm. The maximum settlements of both single-track and double-track tunnels were located at the vault, with a gradual decrease in settlement value towards the surrounding areas. Those findings suggest that regular monitoring of the construction is essential to ensure the safety during the construction process, especially for the settlement of the vault.
