dc.description.abstract 이 연구에서는 보령화력발전소 방수로 수중방류구조에 대한 수리모형실험을 수행하여 수중방류구조 내 흐름 특성을 고찰하고, 수평 유공판 설치에 따른 거품저감 효과를 검토하였다. 수중방류구조 내 단면평균유속은 설계시 거품의 외해 유출 방지를 위해 고려한 목표값 1 m/s 이내에 분포하였다. 또한, 수중방류구조 내 2차 낙하 위치에 수평 유공판을 설치함에 따라 거품의 수중 최대관입깊이가 30~50% 감소함을 확인하였다. 특히, 2차 낙하 위치에 구멍의 크기가 20 cm 정도인 사각구멍형 유공판을 설치하고, 중앙부는 무공 구조로 제작하여 낙하 에너지를 소산시키게 될 경우, 가장 효과적으로 수중에 관입되는 거품 발생량을 저감시킬 수 있을 것으로 기대된다. In this study hydraulic experiment was carried out to investigate the flow characteristics in the submerged outlet structure of Boryeong power plant and the efficiency of bubble reduction by installing horizontal porous plate in the outlet structure. The cross-sectional mean velocity in the submerged outlet structure was smaller than 1 m/s, the target value at the design stage to prevent bubble outflow to the open sea area. In addition, it was found that the maximum depth of bubble penetration is reduced 30 to 50% by installing the horizontal porous plate at the second falling location in the submerged outlet structure. It is expected that the total bubble amount entrained in the water will be most efficiently reduced by installing square-hole-shape porous plate of 20 cm hole size and making its central section as non-porous structure to dissipate the energy of falling water. -
