摘要
本文在理论上分析了超声导波在土壤中的传播特性,计算出L(0,1)模态可以用来对接地体进行检测。同时建立实验系统,对直径12 mm,长2 m的接地体,在土壤、含石土壤、湿润土壤等不同环境下进行检测,实验结果表明,超声导波可以适用于干燥土壤环境下输电线路接地装置缺陷的检测,具有一定的工程实用价值。
Propagation characteristics of ultrasonic guided wave of grounding device for electric transmission line were studied. It was indicated that longitudinal mode L(0,1) could be used in the inspection of bolt embedded in soil.At the same time, the experiments with bolts 12 mm in diameter, 2 m in length embedded in different soil such as soil, soil of containing stone and wet soil detected using ultrasonic guided waves were carried out. It was shown that Ultrasonic Guided-wave can been used for the inspection of construction flow of bolt embedded in dry soils, this method is practically valuable.
