Abstract Based on a certain constructing running shield tunnel of Beijing metro side-crossing close to a high-rise building，using the finite element method calculation model and site monitoring method，the foundation characteristics of the high-rise building affected by the constructing shield tunnel are studied. In different construction stages，the variations of the foundation settlement and inclination of the high building are analyzed. The simulation results show that stratum vertical displacement has a sudden change near the high-rise building. Away from the building in an enough distance，the displacement curve becomes flat. From site monitoring results，the high-rise building inclined to the direction away from the tunnel prior to the shield closing to the building，while the building inclined towards the tunnel during shield crossing. The settlements of the monitoring points reach the maximum value when the shield is 10.0 m away from the monitoring surface. However，the settlements declined significantly when the shield is more than 60.0 m from the monitoring surface，and finally becomes stable. The simulation and the site monitoring results agree well. The conclusion would be helpful for the future similar shield tunneling projects.
