In this paper, we deal with the application of borehole sonar to evaluate the shape of foot protection around the tip of the bored pile. We measured reflection waves at 24 points at intervals of 15 degrees in the pile using a sonar set in the hole. Five kinds of model foot protection and a prototype were used for the experiments. We found that the shape of the five kinds of model foot protection were caught clearly by analyzing the reflection waves. And we confirmed that it was true for the case of the prototype in the field.
