摘要
简单阐述了厚层黄土地区钻孔灌注长桩的一种施工方法,通过对桩基础在这种特定施工工艺下的受力分析,得出了成桩后先使黄土地基湿陷而产生的负摩阻力会对桩基后期承载力产生有利影响的结论。
A construction process of long-bored pile in deep loess is introduced simply. Through the mechanical analysis to the pile foundation in the special process of construction, it is concluded that the negative friction of long-bored pile from collapsibility of loess has contribution to the late bearing capacity of pile.
