| Abstract: | The method of reflect wave is used to examine the cement mixed-in-place pile in the roadbed of Lian-lin Highway. The reflect wave signal has 4 types, which are differently corresponding to the reflect features of the pile top, pile body defect and the pile bottom. Based on theoretical study and practical experiments , we believe that the reflection wave method is effective in examining the cement mixed-in-place piles. |
