文章提出了一种用实测桩顶瞬态激励响应信号识别桩身形状的方法。该方法能定量确定桩身缺陷的位置,延伸范围以及严重程度,从而为基桩桩身质量检测提供了一种新的可靠手段,文中给出了3根模型桩桩身缺陷的识别实例。
In this paper, a method to identify the shape of pile body by using measured transient excitation signal of pile top is proposed. The method can quantitatively determine the position, the extension range and the severity of the pile body defect, so as to provide a new reliable measure for the pile body quality inspection of the pile body. An example of identifying the defects of the three model pile bodies is given in the paper.
