Optimal Designe of Retaining Structure for Foundation Pit with Ring Beam Bracing

Abstract:

After analyses on alternatives of deep foundation pit for UNION HOSPITAL SURGERY WARD BUILDING, the alternative of using brake truss as retaining structure for foundation pit with ring beam bracing was put forward. This retaining structure has great stiffness, little deformation and reasonable fore distribution. It can well control the displacement around the supporting piles and make pit excavation convenient.
