摘　　要：设计了一种用于混凝土无损检测的超声波检测仪,介绍了超声波检测的基本原理和系统设计,着重讨论了其发射系统和接收系统的设计方案,进行了无缺陷和有缺陷混凝土灌注桩的测试实验,并对测试数据及波形分析处理。从实验结果表明,该测试仪检测混凝土缺陷快速准确,误差小,具有一定的实用价值。A type of ultrasonic inspector used in concrete nondestructive inspection is designed. The basic principle of ultrasonic inspection, as well as system design, is introduced. The design schemes of emission system and receiving system are emphasized to discuss. Testing experiment on non-defect concrete-grouted pile and defect one is carried on, and the text data and waveforms are analyzed. The results indicate that this inspector can detect concrete pile defects fast and exactly with small error. It provides engineering ap- plication value.
