摘要
提出利用钢杆超声柱面导波技术对地脚螺栓进行检测的方法。介绍柱面超声导波的频散特性,制作含有不同深度缺陷的地脚螺栓模拟试样,采用相控阵超声柱面导波技术对模拟试样进行检测,分析不同频率探头和混凝土包裹情况对检测结果的影响,建立地脚螺栓的腐蚀损伤评价体系,实现了在役输电线路铁塔埋地地脚螺栓不开挖条件下对其腐蚀状况的检测。
This paper presents a method of testing anchor bolts by ultrasonic cylindrical guidance technology,introduces its characteristics and makes the simulated samples with different depth defects.The simulated samples are tested by phased array ultrasonic cylindrical guidance technology.The influence of probes for different frequencies and concrete wrapping on the test results is analyzed.The evaluation system for the corrosion damage of the anchor bolts is established,which can be used for the the detection of the corrosive wear of the buried anchor bolts for the transmission line towers.
