剪力墙结构桩筏基础设计探讨

Discussion on design points of pile raft foundation of shear wall structure

对剪力墙结构桩筏基础设计中不同布桩方式影响单桩反力进行了探讨,借助通用工程软件分析其原因,提出优化布桩方法的具体步骤,探讨总结此布桩方式的优点,结合工程实例比较,验证在剪力墙下集中布桩能优化工程桩桩数。同时对桩筏设计中碰到的角桩冲切承载力不足、桩筏筏板优化等问题进行探讨。

Discusses the influence of different pile arrangement methods on the single pile reaction force in the design of the piled raft foundation of the shear wall structure,analyzes the reasons with the help of general engineering software,proposes the specific steps of the optimized pile arrangement method,summarizes the advantages of this pile arrangement method,and combines the engineering Examples are compared to verify that concentrated piles under the shear wall can optimize the number of piles in the project.At the same time,the problems of insufficient punching bearing capacity of corner piles and optimization of piled rafts encountered in the design of piled rafts are discussed.
