摘　　要：超声波的波速等参数在不同介质中有较明显的差异,在混凝土中传播时其声学参数与混凝土的密实程度存在密切的关系,根据所采集的声学信号及参数的变化情况可以反映出混凝土中介质的变化情况,从而达到判断基桩完整性的目的。结合某仓库钻孔灌注桩的基桩检测,介绍了超声波检测的应用,并对声波法在基桩检测中的基本理论、检测方法及判别标准进行了分析。Velocity and other parameters of ultrasonic wave could show the obvious differences in different media. When ultrasonic wave propagates in concrete,acoustic parameters have high correlations with the density of concrete. According to the acquisitions of acoustic signals and acoustic parameters,the changes of the medium inside the concrete can be found so as to determine the integrity of the bored piles. Taking the bored pile testing of a warehouse as an example,this paper introduced the ultrasonic testing technology in the bored piles,also analyzed the primary theory,test method and discriminating standard of the ultrasonic testing technology in the cast- in- situ bored piles.
