摘　　要：声波透射法和磁法等方法在检测灌注桩桩长和完整性方面目前已经较为成熟,但截至目前,利用声波透射法检测预应力管桩桩长的应用极少。论文讲述应用声波透射法探测预应力管桩的桩长,阐明应用声波透射法的检测原理及其相关数据处理方法。通过工程实践可得出,声波透射法在探测预应力管桩桩长方面的应用是有效、可行的。Acoustic transmission method and magnetic method have been mature in detecting the length and integrity of cast-in-place pile,but so far,the application of acoustic transmission method to detect the length of prestressed pipe pile is very few.In this paper,the acoustic transmission method is used to detect the pile length of prestressed pipe pile,and the detection principle and related data processing method of acoustic transmission method are expounded.It can be found that the acoustic transmission method is effective and feasible in detecting the pile length of prestressed pipe pile by application analysis and engineering practice.
