摘要
本文分别以海利(Hiley.A)、格氏动力打桩公式和波动方程Smith法分析了52根工程桩的极限承载力,并将其与静载荷试验结果进行统计对比。提出了动测承载力的回归修正公式。给出了各种动测方法的统计参数。
In this paper, the ultimate bearing capacity of 52 engineering piles is analyzed by means of the H(?)'s dynamic pile driving formula and the wave equation of Smith's method.The results are statistically compared with what obtained from the static loading tests.A formula to modify the dynamically measured bearing capacity of piles is proposed, and the statistical parameters for various dynamical measuring methods are also given in this paper.
