Discuss the Vibration Frequency Reflection Wave Method of Low-Strain to Complete the Influence of Pile Inspection

Abstract:

As the main method of the foundation pile low strain dynamic test, the reflected wave method has been widely recognized in engineering after years of research and application. Among the many elements of affecting quality of pile foundation, the influence of excitation frequency on pile inspection is research focuses in this paper. This paper analyzes and summarizes the rules of the effect the exciting force produces in low strain integrity testing by using laboratory simulation experiment.
