Abstract

In this study, the stability of low crested structure armoured by rock has been investigated using two-dimensional hydraulic model tests. The effect of wave steepness and freeboard on the rock stability on crest, front, and the rear slope has been investigated. Rocks were mostly damaged near the upper part of the seaward slope and the crest of the seaward side. From the experimental data, the new empirical formula for the stability coefficients of the rocks was proposed.

본 연구에서는 피복석으로 피복된 저 마루높이 구조물의 안정성을 검토하기 위해 2차원 수리실험을 수행하였다. 피복석 안정성은 구조물 상부, 전사면 및 후사면을 대상으로 파형경사와 여유고를 변화시키며 검토하였으며, 피복석의 주된 피해는 전사면 상부와 바다측 마루부에서 발생하였다. 수행된 2차원 실험결과를 이용하여 파복석의 안정계수 산정을 위한 경험식을 제안하였다.
