摘要
结合焦郑高速公路钻孔灌注桩的超声波检测,对超声波检测的原理、方法以及桩身缺陷的判定进行了介绍和分析,通过实例证明超声波检测法能准确判断出桩身缺陷的位置和范围,并能对缺陷严重程度做出评价,是检测灌注桩桩身质量的一种较好方法。
Combined with the ultrasonic testing of the cast-in-place bored pile in jiaozheng Highway, the paper introduces and analyzes not only the application steps of ultrasonic transmission but the judgment of defect in pile. By the example prove that ultrasonic transmission can judge the location and the range of defect exactly and evaluation of the degree of defect. It is a good way to inspect the quality of cast-in-place piles.
