Abstract—The low-strain impact method is one of the most commonly used nondestructive geophysical methods in pile integrity testing. Data analysis of the low-strain method in the frequency domain allows a researcher to obtain additional information about a foundation. The authors of this article propose a methodology for assessing the contact of piles with soils based on an analysis of the dynamic attributes of the frequency response. Conclusions drawn from using the above-described method can be used by engineers to study the quality of piles and to plan direct static load tests to determine the bearing capacity of piles.

通过声信号的动态属性评估桩与土壤之间的接触

摘要—低应变冲击法是桩身完整性测试中最常用的无损地球物理方法之一。频域中低应变方法的数据分析使研究人员可以获得有关基础的其他信息。本文的作者基于对频率响应的动态属性的分析，提出了一种评估桩与土壤接触的方法。工程师可以使用上述方法得出的结论用于研究桩的质量，并计划直接静载荷测试以确定桩的承载力。
