Abstract

Two-dimensional hydraulic model experiments on rubble mound structure armoring with the tetrapods and the superstructure were conducted to investigate wave transmission characteristics under irregular wave conditions. The previous studies about the wave transmission coefficients dealt with the low crested structures, therefore the rock was the main armor units and the superstructure was not constructed. In this study, the new empirical design formula for the wave transmission coefficient about rubble mound structure with the tetrapods and the superstructure was suggested and the effects of wave steepness and the row of the tetrapods in front of the superstructure could be considered.

본 연구에서는 상치콘크리트가 설치된 TTP 피복 경사식 구조물에 대한 전달파고계수 산정식을 도출하기 위하여 2차원 수리실험을 실시하였다. 기존에 제시된 경사식 구조물에 대한 전달파고계수 산정식은 대부분 국외에서 수행된 저천단 구조물에 대한 연구성과이다. 기존 연구에서는 피복재로 대부분 피복석이 적용되었고, 상치콘크리트가 설치되어 있지 않은 경우이다. 이로 인해 국내 경사제 설계시 적용되는 단면형상과는 많은 차이가 발생한다. 본 연구에서는 국내 경사식 구조물의 설계동향에 부합하는 전달파고계수 산정식을 제시하였으며, 파형경사의 영향 및 상치콘크리트 전면에 거치되는 TTP의 거치 열수에 따른 변화를 고려하였다.
