현장관측 및 수치시물레이션을 통한 해상교량 주변의 조류 유속 분석

Abstract

In this study, the characteristics of the flow speed including the maximum and the average values of tidal current speed and the characteristics of tidal currents by layer were analyzed. For this purpose, speed of the tidal currents around Yeosu Dolsan Bridge, Incheon Bridge, and Yeongjong Bridge were observed for a period longer than a month the flow speed around these bridges, among the major domestic offshore bridges, are known to be high. The observations were intended for the development of a small-scale tidal current power generation system using the piers that are substructures of the offshore bridges that connect land with an island or an island with an island. In addition, a regional operational modeling system (ROMS), a numerical model of coastal hydrodynamics, was established for Yeosu and Incheon waters and was corrected using observation data then, a long-term simulation was carried out to calculate the highest annual flow speed. The data obtained by analyzing the speed of the current approaching the offshore bridges were used for analyzing the tidal currents around the bridges as an open boundary condition of the numerical analysis model. The data obtained by observing the surroundings of the bridges were used for verifying the result produced by the numerical analysis model. The results of this study may be used in the development of a small-scale tidal current power generation system as mentioned eaYeosu Dolsan Bridge, Incheon Bridge, and Yeongjong Bridge were observed for a period longer than a month the flow speed around these bridges, among the major domestic offshore bridges, are known to be high.
