频率域中桩基完整性定量分析

Quantitative Anlysis on Pile Shaft's Perfection in Frequency Domain

通过对不同桩底支承情况下桩基瞬态频率方程的分析,将缺陷截面处假定为缺陷以上桩身的支承,推导出了量化桩基完整性的公式.实际应用表明,该方法可取得良好的工程效果.

By analyzing the transient state of pile foundation's frequency equation, this paper puts forward a supposition that the section in defect is regarded as support of the part above the defective. On base an equation of quantitative perfection of pile foundation is obtained. Engineering applied shows that this method is valid.
