摘　　要：介绍了跨孔透射法检测灌注桩桩身完整性的原理、方法和现场检测技术。通过现场检测实例,利用声波曲线判定桩身混凝土质量及缺陷的可疑位置,并采用PSD判据法进行辅助分析,从而达到判别桩身缺陷性质及范围的目的。结果表明:跨孔透射法判断基桩完整性,其检测过程简单、结果直观可靠,为桩身混凝土质量提供了一种有效的检测方法。The priciple test technology in site of ultrasonic transmission method for detecting integrity of large-diameter cast in place piles are introduced.and combining the engineering case,the qualityof pile body concrete and the possible positions of pile defects are detected by ultrasonic curve;and used the PSD criteria as aidedanalysis,the nature and range of pile defects are estimated.he result indicated：The cross hole transmission method judgment foundation pile integrity, its examination process is simple, result direct-viewing reliableo Thus,it is an effective inspection method for the quality of pile body concrete.
