| 摘 要： | 本文介绍了混凝土结构的压电体波和表面波检测的主要进展,对两种压电声波检测的优缺点进行了总结。体波检测设备一般埋入混凝土内部,需要选择合理的检测部位,检测结果较为精确;声表面波检测无需选择特定的部位,但是检测深度有限。在实际检测工作过程中,可以联合两种方法相互验证。

| Abstract: | This paper introduces the main progress of piezoelectric bulk wave and surface wave detection of concrete structure,and summarizes the advantages and disadvantages of the two kinds of piezoelectric acoustic detection.Body wave detection equipment is usually embedded in concrete,so it is necessary to select a reasonable detection location,and the detection results are more accurate;surface acoustic wave detection does not need to select a specific location,but the detection depth is limited.In the actual detection process,the two methods can be combined to verify each other. |
