Abstract

The runup height is an important design parameter to determine the crest elevation of coastal structures and seawalls. In this study, two dimensional wave runup tests for rubble-mound structure covered by tetrapods were conducted. Incident waves at the toe include nonbreaking, breaking and broken random wave conditions. A empirical formula to predict runup elevation of rubble-mound structure with 1:1.5 front slope was proposed on the basis of physical model test results using a surf similarity parameter. The test results from this study were compared with those from van der Meer and Stam(1992).

파랑의 처오름높이는 항만 및 호안구조물의 마루높이 산정에 있어 주요한 설계요소이다. 본 연구에서는 TTP로 피복된 경사식구조물을 대상으로 2차원 수리실험을 수행하였으며, 실험에 적용된 실험파는 불규칙파로서 구조물 toe 위치에서 비쇄파, 쇄파 및 쇄파된 파의 조건을 포함한다. 본 실험결과를 이용하여 사면경사 1:1.5인 경사식구조물의 처오름높이를 산정할 수 있는 경험식을 쇄파 유사성 매개변수를 이용하여 제안하였다. 그리고 본 실험결과는 기존 연구결과인 van der Meer and Stam(1992)의 결과와 비교하였다.
