In this study is if the design of outlet conduit was appropriate or not by analyzing flow characteristic of outlet conduit with performing hydraulic model experiments. As the results of hydraulic model experiments, the capacity of outlet conduit of elementary design was under estimated, and the designed values of the capacity of outlet conduit of preliminary design based on the values of elementary design was nearly equal to the values of experiments, so the propriety of design was identified. In addition, as the results of examinations of negative pressure of outlet conduit, and propriety of longitudinal sections, the resulting values were within the maximum permissible limits, so it was proved that the design was appropriate. In the base of such processes, the propriety of scale and location of outlet conduit of preliminary design was examined.
본 연구에서는 수리모형실험을 실시하여 방류관의 흐름특성을 분석 방류관 설계의 적정성을 검토하는데 있다. 수리모형실험 결과 기본계획의 방류관 통수능은 과소설계 되었고, 이를 토대로 설계 변경한 기본설계의 방류관 통수능 설계치는 실험치와 거의 일치하여 적절하게 설계되었음을 알 수 있었다. 또한 방류관 부압발생 여부 및 종단형상의 적정성을 검토한 결과 허용치 이내 값이 발생되어 적절한 것으로 판명되었다. 이러한 과정을 토대로 기본설계의 방류관 규모 및 위치가 적절하였음이 검토되었다.
