Abstract: This paper presents a case history of the Nanluogu Subway Tunnel construction in Beijing Metro No. 6 project. An old residential buildings are located right above the proposed the tunnel. The potential risks during the tunnel excavation are identified and the measures that mitigating those hazards are presented. The combination of the large diameter steel pipe shielding and the deep hole grouting methods are proved to be successful. The use of the shield support is critical to the safe excavation of the tunnel when is close to the residential buildings. It is also an effective protective measure for the deformation control of the buildings on the ground.
