超声探测缺口梁损伤和断裂特性试验研究

Test Study of Ultrasonic Detecting Damage and Breaking Features of Concrete Notch Beams

利用超声波技术并辅以电测法对 2组不同开口深度混凝土缺口梁的损伤断裂特性进行了试验研究。试验表明 ,超声法能够综合反映混凝土内部裂缝的扩展规律 。

Engineers adopt the ultrasonic technique, matched with the electrometric method, to study damage and breaking features of two concrete notch beams which have different open depths. Results indicate that the ultrasonic method can comprehensively reflect expansion rules of internal cracks of concrete and that this method is useful for the dynamic mechanism study of damage and breaking of beams.
