本文叙述用动测法预测大直径灌注桩的承载能力的基本原理,分析动刚度与静动对比系数及单桩在容许荷载下容许沉降的取值,最后介绍三个处于不同情况下的大直径灌注桩静动对比试验的实例。
This paper describes the basic principle of predicting the bearing capacity of large-diameter cast-in-place piles by dynamic test, analyzes the comparison coefficient of dynamic stiffness and static motion and the allowable settlement of single piles under permissible load, and finally introduces three large diameters under different conditions. Example of Static Contrast Test for Cast-in-place Piles.
