A Study on the Application of NDT(Non-Destructive Testing) Techniques to the Unknown Bridge Foundations
미지의 교량기초에 대한 비파괴 시험기법(NDT)의 적용성에 관한 연구
Abstract
In this study, ten drilled shafts were constructed for evaluating the application of NDT(Non-Destructive Testing) techniques. The drilled shafts, 0.4 m in diameter and 7.0 m in length, were constructed at Namyangju site in Namyangju City. One of the shafts was constructed with no defect, and the other shafts were constructed with the defects of soft bottom, necking, bulging, cave-in and/or weak concrete. Then, these techniques were applied to the bridge foundations for studying unknown bridge foundation characteristics.
