摘　　要：既有建筑的桩基检测是一项较为困难的工作,旁孔透射波法可以有效解决这种检测所面临的困难。本文中对某已建工程桩基建立ABAQUS数值分析模型,研究了基于旁孔透射波法对桩体埋深进行检测的影响因素。研究结果表明,旁孔透射波法检测所得的桩体埋深值误差随着桩长的增大逐渐减小,当桩长为24.0m时检测所得的误差均小于2.5%。The pile foundation detection of existing buildings is a difficult work, while the side hole transmission wave method can effectively solve this difficulty. In this paper, ABAQUS numerical analysis model is established for the pile foundation of a built project, and the influencing factors of pile buried depth detection based on side hole transmission wave method are studied. The results show that the error of pile buried depth measured by side hole transmission wave method decreases gradually with the increase of pile length. When the pile length is 24.0 m, the error is less than 2.5%.
