摘要
在分析已有大坝CT测试系统的基础上,配置了由超磁致震源、串式超声波换能器及超声仪组成的声波CT测试系统.该系统方便、实用,解决了大坝混凝土CT探测中传播距离与检测分辨率之间的矛盾.
Based on the analysis of the dam CT testing system, the acoustic CT testing system collocated with giant magnetostrictive vibration source, serial ultrasonic reception transducers and ultrasonic instrument is presented. This system has the advantage of convenience and practicality. It can solve the contradiction between spreading distance and testing precision when applied to detect dam concrete with acoustic CT.
