摘　　要：以金茂大厦和上海环球金融中心的成功设计经验为依据,从设计角度分析和评价中国第一高楼——上海中心大厦桩筏基础的性状及安全性。类比分析大楼的重量、水浮力和桩土分担,并着重对桩承载力和桩顶反力、筏板厚度和弯矩、建筑物沉降等进行计算和评价,综合分析认为上海中心大厦的桩筏基础具有较高的安全度。其分析思路、计算方法及所得结论可为今后超高层建筑桩筏基础的设计和性状研究提供参考。Based on the successful design experience of Jinmao Building and Shanghai World Financial Center,this paper attempts to analyze and evaluate the behavior of piled raft foundation for Shanghai Center Tower from the design perspective.The weight of the building,buoyancy of the water and load-sharing between pile and soil are analogously analyzed.Capacity of pile,load on pile group,thickness and bending moment of raft,settlement of piled raft are calculated and analyzed especially.The analysis thinking,methods and results can be served as references for design and study of piled raft foundation for super-tall buildings.
