| Abstract: | 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. |
