竖向荷载下后压浆桩承载性状的数值分析

Numerical Analyses on the Bearing Character of Base-grouted Pile in Vertical Loading

摘要:

利用弹性有限元法对桩底后压浆桩的工作性状进行分析，研究讨论压浆作用、桩体在不同加荷阶段的力学状态以及影响压浆桩竖向承载力的主要因素，并对其提高承载力的效果进行了评价，得出一些有益的结论。

Abstract:

This paper makes a thoroughly study on the behavior of base grouted pile in vertical loading by FEM. The grouting effect and mechanical character of based grouted pile in varied loading term and analyzed. Some conclusions relating to the base grouted pile are obtained from simulating the influence of several factors.
