| Abstract: |
| 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. |
| Key words: ultrasonic CT,detection of defects,images of CT,concrete, |
