摘要

摘要: 对于灌浆套筒构件，可将灌浆套筒内水泥基灌浆料看作广义上的混凝土，为研究超声波层析成像技术对灌浆套筒构件密实度无损检测的可行性，分别从理论研究、有限元模拟和试验测试三个方面对套筒内灌浆料的密实度进行分析。研究结果表明：超声波将无法直接透过灌浆料全部脱空的套筒传播，而是会按照最短路径发生绕射；因套筒脱空所导致的声速分布图差异化不明显，从声速分布图上无法有效识别密实及脱空状态所对应的低声速区；对于斜口斜导管检测方式，可通过观察斜导管内灌浆料流失情况来推断套筒内灌浆的料密实度情况。

Abstract: For grouting sleeve members, the cement-based grouting material in the grouting sleeve is regarded as the concrete in a broad sense. In order to study the effectiveness of ultrasonic tomography in nondestructive testing of the compactness of grouting sleeve members, the compactness of the grouting material in the sleeve was analyzed from three aspects of theoretical research, finite element simulations and experimental testing. The results showed that:the ultrasonic wave could not propagate directly through the sleeve where the grouting material was completely empty, but diffracted according to the shortest path. The difference of the distribution diagram for sound velocity was not obvious due to the sleeve void, the lower acoustic velocity region corresponding to dense or empty states could not be effectively identified from the acoustic velocity. For the inspection method of inclined ducts with inclined ports, the compactness of the distribution diagram of grouting material in the sleeve could be inferred by observing the loss of the grouting material in the inclined duct.
