Abstract

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.
