방파제의 신뢰성 설계에 의한 중량식의 비교 = Weight comparison by Reliability Design of Rubble Mound Breakwaters

다국어 초록 (Multilingual Abstract)

Hanzawa et a1 (1996)calculated damages of armor blocks using Monte-Carlo simulation for horizontally composite breakwaters. In their calculation, one dimensional wave breaking model by Goda(1975) was used. But in the real sea area, incident waves have variability of wave directions including directional spreading parameter, refraction and deviation of mean wave directions.
In this study, reliability based design was executed using three dimensional random wave breaking model by Kweon(1998) instead of one dimensional wave breaking model by Goda(1975). As a result, considering variability of wave directions, thedamages of armor blocks are calculated to be smaller than those of Hanzawa et a1 (1996). The damages of armor blocks calculated using van der Meer(1988b) stability formula for Tetrapods also show similar results.
Reliability based design for breakwater armor blocks has been executed on the assumption of unidirectional waves. But, if variability of wave directions is considered, the economic design can be expected.
