Abstract The differential deformation after construction caused by foundation settlement and adjacent construction disturbance widely exists in the existing metro shield tunnels in China, it has adverse effects on tunnel structural performance during tunnel service period.Based on Hertz non-linear elastic contact theory to simulate wheel-rail contact relationship, considering spatial structure characteristics and mutual contact relationship of vehicle, track, tunnel and surrounding rock, an integrated calculation model of vehicle-rail-tunnel-surrounding rock was established, and the structural dynamic response caused by train operation after shield tunnel heave deformation caused by foundation pit excavation was calculated.The results showed that the tunnel heave deformation aggravates dynamic responses of track structure and tunnel structure; dynamic stress of lining ring joint concrete at edge and center of foundation pit changes sharply; shear force of longitudinal joint bolt at top and bottom of lining arch is greatly affected, while internal force of circumferential bolt at arch waist changes significantly.

Key words： metro shield tunnel train-track-tunnel-surrounding rock integrated model differential deformation dynamic response
