考虑桩体刺入的复合地基加固区沉降计算方法研究

The Research on the Calculation Method of Composite Foundation Reinforced Area Settlement Considering Pile Body Penetration

荷载条件下桩土之间相互作用造成复合地基加固区沉降计算多存在误差,在桩身压缩计算法基础上考虑桩体刺入量,基于假设侧摩阻力,以单元受力平衡方程为基础推导桩体上穿下刺量,提高沉降计算精度,该思路可为复合地基设计计算提供有益参考。

Based on the calculation method of pile body compression and hypothesis side friction, considering pile body penetration amount, this paper deduced the penetration amount of the pile body based on the unit force equilibrium equation, which improved the accuracy of settlement calculation, and provided a useful reference for the design and calculation of composite foundation.
