超声法结合钻芯法检测大体积混凝土内部缺陷

Detection of mass concrete internal defects by ultrasonic combined with core drilling method

对于大体积混凝土结构,由于其尺寸较大,对其内部缺陷的判定一般采用无损检测方法—超声法,可以充分利用其穿透力强、操作简单的优点。结合钻芯法查找混凝土内部缺陷直观可靠、精度较高的特点,提出了超声法结合钻芯法检测大体积混凝土内部缺陷的试验研究,丰富了检测方法,提高了检测效率。

The massive concrete structure,due to its larger size,detection of its internal defects commonly used NDT methods-ultrasonic.Which can make full use of its penetrating power,as well as the advantages of simple operation.Combination of concrete core drilling method to find internal defects in intuitive and reliable,high precision characteristics.Detection of mass concrete internal defects by ultrasonic combined with core drilling method in experimental research,which enrich the detection methods and improve the detection efficiency.
