摘　　要：桩基属于地下工程,施工过程中隐蔽性高,施工质量很难控制,如何更好的检测基桩完整性,保证桩基质量是一项重要课题。通过声波透射法在蒙华铁路基桩检测中的应用实例,分析了声波透射法检测出基桩的几种缺陷,采用低应变方法辅助检测进行了对比,又通过钻孔抽芯法进行了验证,更加证明了声波透射法检测基桩质量的可靠性。Pile foundation belongs to underground engineering.It is difficult to control the construction quality because of its high concealment in the construction process.How to better test the integrity of pile foundation and ensure the quality of pile foundation is an important topic.In this paper,through the application of the acoustic transmission method in the foundation pile detection of the Mongolian Chinese railway,several defects of the foundation pile detected by the acoustic transmission method are analyzed.The low strain method is used to assist the detection for comparison,and the drilling core pulling method is used to verify,which further proves the reliability of the acoustic transmission method in the detection of the quality of the foundation pile.
