영문 초록

Hydraulic experiment was executed to identify the souring range of bride pier. The experiment categorized three kind of bridge pier shape, that is composed of circle shape, square shape and the special shape. Measured scouring data was compared with the results by empirical CSU formula which was generally used in practice. As empirical formula could not consider backfill, measured scouring range is by far smaller than results of CSU formula. Therefore in case of design anti-scouring structure, there is the possibility of overestimation in case of using empirical formula.
