[摘要] 介紹了超聲法檢測混凝土密實度的方法和一般步驟，重點討論并分析了一個典型的大橋箱形梁混凝土密實度的檢測。對檢測結(jié)果進行綜合分析和整理后可得，超聲法檢測混凝土密實度的技術(shù)適應(yīng)范圍更寬、檢測精度更高、可操作性更好。希望對同類型構(gòu)件的檢測方法提供一定的借鑒作用。

Abstract: The testing methods and steps by ultrasonic method acted on concrete compactness were introduced. A typical detection of bridge box concrete compactness was discussed and analyzed. Through analyzing on the inspection result synthetically, a conclusion was got that the ultrasonic technology acted on concrete compactness has more wide range application, higher testing precision, and better maneuverability, which could be used as reference in similar members.
Keywords: ultrasonic method; detection; box-beam; compactness
