基于共同作用理论的核心筒下桩-承台基础优化设计

Optimizing Design of Pile-raft Foundation Under Core Tube Based on Cooperative Effect Theory

基于共同作用理论,结合实际工程,采用有限元法对核心筒下桩-承台基础的荷载分担比例及受力特点进行了较为详细的计算和分析。依据分析得到的规律对常规设计方法进行了优化。证明考虑上部结构-承台-桩-土共同作用来设计核心筒下桩-承台基础是合理的,也是必要的。可供类似工程设计参考。

Based on the theory of cooperative effect, combining with a practicality engineering, the participance in load and the loading-carrying characteristic of the pile-raft foundation under core tube are analyzed by finite element method. It has proved to be reasonable and necessary to design the pile-raft foundation under core tube considering the theory of upside structure-raftpile-soil interaction, and the results can be reference to foundation design of similar engineering.
