摘　　要：对旧桥基桩的质量检测是一个老大难问题,目前还缺乏简单、有效的方法。从理论上分析了采用扭转波法检测旧桥基桩桩身完整性的可行性。探讨了上部构造物对扭转波信号传播的影响,并通过现场实测验证了该方法的正确性。The testing for pile foundations of old bridges is difficult because there is not any simple and effective method. In this paper, theoretical analysis has been conducted on the feasibility of application of torsion wave method on pile foundation testing for old bridges. The impact of superstructure on torsion wave signal spreading has been explored, and through on-site measurement the proposed method has been verified.
