超声波检测基桩完整性各声学参数权重的探讨

Discussion on the Weight of Acoustic Parameters in Ultrasonic Testing of Foundation Pile Integrity

桥梁工程的基桩完整性检测大多采用无损检测,声波透射法具有可靠性高,不受桩长影响而得到广泛应用。将介绍声波透射法的原理,声学参数的代表意义和通过三个工程实例讲解各声学参数权重的分析,为混凝土桩基础检测提供参考依据。

Most of the foundation pile integrity testing of bridge engineering adopts non-destructive testing.The acoustic transmission method has high reliability and is not affected by the pile length and is widely used.This article will introduce the principle of the acoustic transmission method,the representative meaning of the acoustic parameters,and explain the analysis of the weight of each acoustic parameter through three engineering examples,and provide a reference for the detection of concrete pile foundations.
