摘要
在混凝土表面损伤层厚度的超声波检测中 ,采用回归分析的方法取代传统的作图法 ,能进一步提高检测精度。对埋有钢筋的混凝土表面损伤层的厚度进行检测 ,指出了钢筋对检测的影响程度。当换能器连线与钢筋轴向成斜角布置时 ,能避免钢筋的影响。
Regression analysis method was used in ultrasonic thickness measurement of superficial damage layer in concrete. The influence of the steel in reinforced concrete on testing was studied, which could be avoided when the arrangement line of transducers was laid in an oblique angle with the bar axis.
