筏式和箱式承台弯矩的计算

Bending Moment for Piled Raft (or Piled Box) Foundation

本文通过现场测试以及高层建筑桩筏和桩箱基础的共同作用分析,提出了高层建筑桩筏(箱)基础底板的厚度、相对弯曲以及整体弯矩的确定方法。文中还给出了基底反力的统计值,角桩反力、边桩反力与桩的平均反力的比值的统计值,以利设计人员的使用。

A calculating method for determining the thinkness of foundation slab, relative deflection and whole bending moment for piled raft (or piled box) foundation for tall building is presented by means of field measurements and analysis of interaction between superstructure and piled raft (or piled box) foundation. The statistical values of the contact pressure, ratio of corner and side pile load to the average load are also given for the use of designers in practice.
