摘要: 为掌握地基土的沉降对桩身负摩阻力的影响,基于现场试桩基本情况,研究荷载条件的变化对单桩负摩阻力的影响趋势,运用ABAQUS数值分析软件对研究区域桩基负摩阻力的变化规律及发展进行有限元模拟。参照有限元模拟分析的结果,综合得出桩基础在不同环境下的长期受力特征,为优化加强基础构件的承载力提供参考设计依据。

Abstract: In order to explore the influence of the settlement of the surrounding soils on the pile negative side friction and to investigate methods reducing the potential impact, the numerical simulations were performed on development of the negative side friction in piles under loading conditions by using commercial software ABAQUS based on the field pile static loading test results. The long term loading condition of piles in recent fills are also demonstrated.
