Abstract

Two-dimensional laboratory experiments were conducted in a wave flume to investigate the wave transmission phenomena of rubble-mound type submerged structures armored with Tetrapods. Different experimental conditions were included by considering relative crest depth, relative freeboard, relative crest width, wave steepness, and so on. An empirical formula was proposed to predict the wave transmission coefficients over various specifications and structural designs of the partial perforated (rubble-mound) type submerged structure from the experimental results. The proposed formula successfully predicted the wave transmission coefficients. In this study, the proposed empirical formula of the wave transmission over the rubble-mound type submerged structure was improved from the existing formula.

Tetrapod로 피복된 경사형 수중구조물을 대상으로 파랑의 전파현상을 검토하기 위해 2차원 수리실험을 수행하였다. 수리실험은 수중구조물의 서로 다른 상대여유수심, 상대여유고, 상대상단폭 및 파형경사 등을 적용하여 수행되었다. 수리실험결과를 이용하여 경사형(부분투과형) 수중구조물에 대한 파고전달계수 산정식을 제안하였다. 제안된 경험식은 경사형 수중구조물의 파고전달계수를 충분한 정도로 예측함을 확인하였으며, 기존 경험식을 개선하였다.
