摘要
介绍了超声波CT的原理、反演算法、测线布置以及网格划分,利用所编制的超声波CT程序对某工程桩的一段进行层析成像,给出了测区混凝土超声波CT成像图—等值线和色谱图,据此确定质量异常区的位置、尺寸,以推断混凝土内部缺陷.
The principle of ultrasonic CT, inverse methods, layout of test lines and meshes division are introduced. A segment of a pile was detected with ultrasonic CT, with images of CT including isoline and chromatogram produced by using a calculation program developed by the authcrs. According to the images, the location and dimension of abnormal quality sections are identified, and the interior defects of concrete structures deduced.
