본 연구에서는 사석, cube및 tetrapod를 대상으로 불규칙파를 적용하여 경사식방파제의 피복재 안정성에 대한 2차원 실험을 수행하였다. 파복재 중량산정식으로는 Hudson식과 van der Meer식을 대상으로 하였으며, Hudson식은 규칙파, van der Meer식은 불규칙파를 적용한 실험으로부터 얻어진 식이다. 본 연구의 목적은 실험결과를 이용하여 Hudson식과 van der Meer식을 비교 검토하는 것이다
In this study, the stability of armor blocks of rubble-mound breakwaters is investigated based on the 2-dimensional hydraulic model test with irregular waves. Amor blocks were used the three types; rock, cube and tetrapod. And Hudson formula and van der Meer formula which are used for calculating the weight of armor blocks are considered. Hudson formula was developed from regular wave tests, while van der Meer formula was developed from irregular wave tests. The purpose of this paper is to compare and test two selected stability formulas using the experimental data.
