摘要: 预应力索孔道密实性是预应力结构工程质量控制的重点,研究了采用X射线数字成像技术(DR)检测预应力索孔道密实性的方法,分析了不同工况对数字成像结果的影响,并通过局部破损法对检测结果进行验证,证明了该方法的可靠性。Abstract: The compactness of prestressed cable duct is the key point of quality control of prestressed structure engineering. The method of using X-ray digital imaging (DR) to detect the compactness of prestressed cable duct is studied. The influence of different working conditions on the digital imaging results is analyzed. The local damage method is used to verify the detection results, indicating the reliability of the method.
