摘要
本文运用弹性半空间无限体的明德林理论和浅基础中的分层总和法,对桩土间滑动采用刚塑性模型,分析了桩-台-土相互作用的机理,并对带台单桩的工作性态作了较详尽的对比及分析。通过与某实际工程试桩资料比较,理论计算p-s曲线与试桩p-s曲线基本吻合,证明了本文计算方法的正确性,计算及分析结果对桩基的设计和研究有较大的参考价值。
In this paper, authors adopt the Mindlin formula for clastic medium, the method of layering summation for shallow foundation and the rigid-plastic slip model between pile and soil to analyse the interaction mechanism between the pile, the cap and the soil and their working character. A comparison of the theoretical result with that of the test in situ shows that the calculated p-s curves are similar to the p-s curves obtained in situ testing. It should be said that the results in this paper are valuable references for researchers and designers working for the pile foundation design.
