Scour Protection Effect around the Monopile Foundation

Abstract

본 연구는 3차원 CFD(Computational Fluid Dynamics)이용하여 모노파일 기초 주변의 환형 세굴방지공에 의한 세굴방지 효과를 파악하였다. Torsethaugen(1975)의 수리모형 실험결과를 바탕으로 FLOW-3D의 해석결과를 검증하였다. 검증결과를 바탕으로 유속변화에 따른 세굴을 연구한 결과, 유속이 증가할수록 최대 세굴심과 세굴폭 또한 증가하는 경향을 확인하였다. 모노파일 기초 주변에 세굴방지 효과 연구를 위해 바닥면에 환형 세굴방지공을 부착하여 수치실험을 수행하였으며, 약 68.5%의 세굴 감소 효과를 확인했다. 또한 하강 유속과 구조물 주변 저층 유속이 감소한 것을 확인하였고, 이는 세굴방지공이 세굴에 영향을 미치는 하강류의 저감 효과를 보이는 것으로 판단된다.
