The interactions between twin shield tunneling and the nearby high rise building were researched by numerical calculation and field monitoring, with the project of Beijing subway line 6 as the background. The place of maximum ground settlement when two parallel tunnels shield construction successive was assessed by using the software FLAC3D. And the influences of the interactions between twin shield tunneling and the nearby high rise building on the ground settlement were analyzed numerically. Further, the field instrumentation were presented and conducted during the tunnels-driven passing through the nearby high rise building successively, and the curves of ground settlement were obtained. The Influences of twin shield tunnel-driven successive on the adjacent structures were analyzed. The results show that the ground rises slightly at 20m ahead of the shield face, and the value of ground settlements is basically constant when the shield face passes cross-section 40m. The value of ground settlements caused by back shield tunneling is larger than it caused by the first shield tunneling. The tall building settlements are influenced greatly by shield construction when the tall building is in the range of tunnel settlement trough, and the settlements have little relationship with the construction sequence of the twin-tunnels. The results from field tests are consistent with numerical simulations, and it will potentially provide the knowledge for understanding tunneling undercrossing the existing tall buildings.
