Abstract

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.

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.
