摘要
通过输电线路基桩质量检测工程实例,介绍了超声波透射法在基桩质量检测中的应用,并就目前超声波透射法中基桩质量评判依据(声速临界值、波幅临界值、PSD值)及实测波形的评判优点和存在的问题进行了分析和探讨。
This paper has dealt with the application of the ultrasonic transmission method to the test of foundation pile in the transmission line project, with some practical examples given concerning the test of foundation pile in the transmission line project. The advantages and existing problems of ultrasonic transmission are analyzed for quality evaluation, which include the critical value of acoustic velocity, the critical value of amplitude, the value of PSD and the measured wave.
