加芯搅拌桩荷载传递机理的研究

Research on load transfer mechanism of concrete-cored DCM pile

加芯搅拌桩是一种用于处理软土地基的新型桩,目前,该种桩型在国内外的研究尚未完善。本文将利用ANSYS有限元软件,对在竖向荷载作用下加芯搅拌桩单桩的工作性状进行数值分析,得出桩身位移、轴力、侧摩阻力沿深度的分布曲线。通过对这些曲线的分析,并结合静载荷试验的数据,对加芯搅拌桩的荷载传递机理进行深入研究。

A new kind of pile named concrete-cored DCM pile is developed for medium load design in soft clay ground, its load transfer mechanism of this new pile is analyzed in this paper. This paper analyzes the working property under the vertical loads by the finite element program ANSYS, and gets the displacement curve, the axial force curve, the frictional resistance curve, and so on. Through profound analyzes to these curves, and the data of the on-site static load tests, we can get the load transfer mechanism of concrete-cored DCM pile.
