摘要

通过对跨孔超声波检测方法的理论探讨

结合工程实例

利用声波曲线判定桩身混凝土质量及缺陷的可疑位置

并采用PSD判据法进行辅助分析

从而达到判别桩身缺陷性质及范围的目的。实践证明

采用跨孔超声波法检测混凝土灌注桩桩身质量

其结果直观可靠

为桩身混凝土质量提供了一种有效的检测方法。

Abstract

Through theoretical discussion of the cross-hole ultrasonic testing method and combining the engineering case

the quality of pile body concrete and the possible positions of pile defects are detected by ultrasonic curve; and used the PSD criteria as aided analysis

the nature and range of pile defects are estimated. Practice shows that the cross-hole ultrasonic method for quality inspection of cast-in-place concrete pile can give visual and reliable results. Thus

it is an effective inspection method for the quality of pile body concrete.
