摘要
论述了支盘桩灌注桩的成桩机理,挤扩支盘灌注桩的现场试验原理及方法,确定了该试验桩型的极限承载力并总结了其沉降的发展规律,为进一步使该桩型在湿陷性黄土中的应用奠定基础。
The pile forming mechanism, the site experimental principle and the experimental method of the squeezed branch pile are elaborated, and the ultimate bearing capacity of the tested pile is determined, the developing regularity of settlement is summarized. The studied findings can prepare the application in collapsible loess area of the same pile type.
