본 논문에서는 세 가지 모형(Owen 모형, Van der Meer & Janssen 모형, Hedges & Reis 모형)을 적용하여 월파의 확률적 평가를 수행하였다. 건설중인 부산 신항 방파제의 월파 확률 예측 값을 도출하는 데에 있어서 Hedges & Reis 모형이 월파에 의한 방파제 파괴 확률분석과 Level II와 Level III 신뢰성 해석을 이용하는 것으로 적합하여 건설비용의 절감을 위하여 파괴가능성이 낮은 월파의 천단고를 제안하였다.
In this paper, three classical overtopping models: Owen model, Van der Meer & Janssen model and Hedges & Reis model were used to calculate the failure probability of wave overtopping of seawalls. Among of them, the Hedges & Reis model was regarded as a moderate method to analyze the failure probability of wave overtopping of seawalls and the probabilistic assessments of wave overtopping were carried out for a constructing seawall at Busan in Korea by Level II and Level III reliability methods. Considering the cost of construction, an appropriate crest level was proposed for a certain rate of wave overtopping at a lower failure probability.
