摘要/Abstract

摘要： 首先根据自平衡试桩法上段桩的受力模型理论分析其荷载传递机理，然后在考虑桩土接触面特性的基础上使用ANSYS有限元分析软件建立上段桩的三维有限元模型对其展开研究，最终得到上段桩在荷载传递机理、沉降变形以及桩身内力分布等方面的规律，还进一步研究了桩土刚度比对桩身截面位移和桩侧摩阻力发展和分布的影响。

Abstract: The load transfer mechanism in the upper portion of the pile during the load tests is analyzed in this paper. A threedimensional numerical analysis model is developed by considering the pilesoil interface properties. The actual load transfer, vertical displacement and stress in the upper portion of the tested pile are obtained. The effect of pile stiffness on the deflection of the pile section and the side friction are also investigated.

Key words: self-balanced pile loading test, upper pile, finite element analysis
