摘要
通过福建医科大学附属协和医院外科病房综合楼基坑支护方案的分析对比,提出采用制动桁架作为深基坑大直径圆环梁水平支撑体系,受力合理、刚度大、变形小,利于控制围护桩位移、方便土方开挖及地下室施工。
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.
