超声波沿空钢管管壁径向传播方式研究

摘要

Based on the defect detection data for steel tube concrete arch bridges and previous research results, the preliminary study is made on the ultrasonic wave spreading way along hollow steel pipe wall according to the test results of the ultrasonic wave propagation velocity in the air and hollow steel pipe wall, and then the radial transmission mode is proposed.%在深入调研超声波用于钢管混凝土拱桥拱肋缺陷定量检测相关资料和现有研究成果基础上,根据相关超声波传播理论,结合超声波在空气中传播速度测试和超声波在空钢管管壁中传播速度测试结果,开展了超声波沿空钢管管壁径向传播方式的初步研究,提出了超声波在空钢管管壁中径向传播方式.
