声波透射法在大直径灌注桩检测中的应用

Techniques of ultrasonic transmission method to large- diameter cast- in- place piles testing

本文探讨了桩基工程中声波透射法检测的测试原理、桩身质量的判别依据。并结合工程实践证明声波透射法对于检测混凝土质量具有精度高、结果直观可靠等优点,为控制钻孔灌注桩的施工质量提供了一种有效的方法。

This paper analyzed the basic principle and the evaluation method of the quality of concrete through ultrasonic transmission method in piles founda-tions. The engineering practice has proved that ultrasonic transmission method for detecting the quality of cocrete has the advantages of high precision, intuitive and reliable results, which provides an effective method to control the construction quality of concrete of cast - in - place pile.
