dc.description.abstract This paper deals with the reliability analysis of foundation for an offshore wind turbine system. Reliability analyses were carried out for suction bucket foundation considering the uncertainties in soil and structural parameters. In reliability analysis, the vertical and lateral resistances are defined as base limit states. The case studies were carried out using the preliminarily designed foundations at western-south mainland sea of Korea. From reliability analyses, vertical resistance for free-slip condition has overall lower reliability index, and submerged unit weight and internal friction angle of seabed soil are governing factors in vertical and lateral resistance in this case. 본 논문에서는 서남해 해상풍력 실증단지 해역을 대상으로 석션버켓기초의 지지력에 대한 신뢰성 분석에 대한 내용을 다루었다. 5MW급 해상풍력터빈의 콘크리트 석션버켓기초를 선정하여 기초 설치 후 연직지지력과 수평지지력에 대한 파괴확률을 계산하고 설계변수의 민감도를 분석하였다. AFOSM을 이용한 신뢰성해석을 수행한 결과, 기초-지반 분리거동 시 연직지지력에 대한 파괴확률이 가장 큰 것으로 나타났으며 기초지반의 단위중량과 내부마찰각이 지배적인 영향인자임을 확인하였다. -
