摘　　要：双肢钢筋是采用两根相同直径的钢筋紧靠并行,并与构件表面平行的一种布筋方式。采用电磁感应法检测双肢钢筋混凝土保护层厚度,与传统的单根钢筋布置方式相比,由于受双肢的影响,检测结果通常存在较大的误差。基于此,本文详细探析了钢筋保护层厚度检测中电磁感应法的应用要点和精度控制措施,有利于保障钢筋保护层厚度的科学性,提升建筑结构性能。Two-legged stirrup is a bar arrangement method that uses two reinforcing steel bars of the same diameter in close parallel to each other and parallel to the surface of the component.The electromagnetic induction method is used to detect the thickness of the concrete cover for reinforcement of two-legged stirrup,compared with the traditional single steel bar arrangement,the detection results of this method usually have a large error due to the influence of two legs.Based on this condition,this paper explores the application points and precision control measures of electromagnetic induction method in the thickness detection of concrete cover for reinforcement,which is conducive to ensuring the scientific thickness of concrete cover for reinforcement and improving the performance of building structures.
