摘要： 为了能更好地判断桩身缺陷位置与桩身长度，本研究结合实际工程，运用单速度法与双速度法对桩基完整性与桩身长度进行探究。结果表明，单速度法和双速度法都可以判断桩身缺陷位置，但双速度法可以更好地作为桩身缺陷的检测方法。单速度法取法判断桩身长度，双速度法可以有效地判断桩身长度。同时，桩身长度在0.1的误差范围内，满足实际工程的设计要求。
Abstract: In order to better judge the location of pile defects and the length of the pile, this study explores the integrity of the pile foundation and the length of the pile with the single velocity method and the double velocity method combined with the actual project.The results show that both single velocity method and double velocity method can judge the location of pile defects, but the double velocity method can be better used as the detection method of pile defects. The single velocity method is used to judge the pile length, and the double velocity method can effectively judge the pile length. At the same time, the pile length is within the error range of 0.1, which meets the design requirements of the actual project.
