[摘要] 介绍了超声法检测混凝土密实度的方法和一般步骤，重点讨论并分析了一个典型的大桥箱形梁混凝土密实度的检测。对检测结果进行综合分析和整理后可得，超声法检测混凝土密实度的技术适应范围更宽、检测精度更高、可操作性更好。希望对同类型构件的检测方法提供一定的借鉴作用。

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
