混凝土灌注桩声波透射法检测技术及其应用

Sonic Transmission for Test of Concrete Grouting Pile and Its Application

声波透射法检测全面、细致,现场操作简便,用于大直径混凝土灌注桩检测,能够准确的判别桩的各类缺陷。本文介绍了声波透射法的基本原理、检测前的准备工作以及检测过程中的注意事项。通过工程实例提出了桩身存在缺陷时声学参数的特征。

At present, sonic transmission is one of the most reliable methods for test of concrete grouting pile with large diameter, which could precisely identify varied defects of piles. This paper demonstrates the basic principle of sonic transmission and the problems to which attention should be given during test. Through on-the-spot test, this paper proposes several features of sonic parameters when pile has defect.
