摘要
采用弹性波反射法检测桩身质量,就是将嵌入地层的桩近似看作一维弹性杆件,在桩顶施加一冲击力,根据应力波的理论,评价桩身质量。论文通过工程实例研究了应用弹性波反射法的波形特征判定预制方桩桩身质量的方法。
Elastic wave reflection method,is the method regarding the embedded pile as one-dimensional staff,applying an impacting force to the top of the pile,to evaluate the quality of the pile according to the theory of stress wave.This article illustrate explain how to evaluate the quality of the pile by the wave line of elastic wave reflection with two examples.
