沈阳市大直径挖扩桩桩端阻与桩侧阻划分方法初探

On the Method to Differentiate Tip Resistance and Lateral Resistance of Large Diameter Reamed Pile in Shenyang City

本文在搜集数根大直径挖孔灌注桩试桩资料的基础上,通过对Q、S数据规律性的分析提出了用Q—S曲线相关直线法划分沈阳城区砂卵石地基上大直径挖扩桩的端阻与侧阻。

The tip and lateral resistances of large diameter reamed piles on sandy gravel ground in Shenyang city to be differentiated by using linear method related to Q-S curve are proposed in this paper through the analysis of regularity of Q and S based on the information of several large diameter excavated cast-in-place piles.
