摘要
本文列举了超声脉冲在混凝土中的传播原理、路径等,根据被测结构物测试面的实际情况,选择不同的换能器布置方式,从而使超声脉冲在混凝土内部有效传播,进而判断混凝土的物理特性,现场模型梁存在多个测试面,故采用对测方法进行测试,根据测试的超声波波速及均方差的数值大小进行计算分析,从而判断混凝土的密实性及均匀性。
This article enumerates the principles of the ultrasonic pulse propagation in concrete, and path, and so on. According to the surface of the test of the structures based on the actual situation, it is to choose a different transducer arrangement, so that the ultrasonic pulse in concrete internal can gain an effective communication, and then to judge the physical properties of the concrete. The model of beam having multiple tests, the testing measurement method is adopted. According to the test~ of ultrasonic wave velocity and the size of the mean square error of numerical calculation and analysis, it is to identify the compactness of concrete and uniformity.
