국내에서는 경사식구조물의 상치콘크리트에 작용하는 파압을 산정하는 지침이 부재함에 따라 간접적인 방법을 적용하여 산정하고 있다. 현재 설계법은 직립식구조물에 작용하는 수평파압에 대한 Goda의 파압산정식과 Takahashi et al.의 소파블록 피복에 따른 저감계수를 적용하여 산정하고 있는 실정이다. 이러한 수평파압 산정법은 명확하게정립된 것이 아니며, 경사식구조물의 상치콘크리트에 작용하는 파압을 직접 산정할 수 있는 방안의 도출이 필요한실정이다. 본 연구에서는 경사식구조물의 상치콘크리트에 작용하는 수평파압을 검토하기 위해 규칙파를 적용한 2차원 수리모형실험을 수행한 후, 규칙파 작용조건에서의 수평파압을 산정할 수 있는 경험식을 도출하였다.
Abstract
In Korea, there are no guidelines for estimating the wave pressure acting on the crown wall of rubble-mound structure, so indirect methods are used. The current design method calculates the horizontal wave pressure by Goda’s formula and the reduction factor of Takahashi et al. This method of estimating horizontal wave pressure has not been clearly established. Therefore, it is necessary to develop a method to directly estimating the horizontal wave pressure acting on the crown wall of rubble-mound structure. In this study, a two-dimensional physical model test under monochromatic wave conditions was performed to examine the horizontal wave pressure acting on the crown wall. Using the experimental results, an empirical formula was derived to calculate the horizontal wave pressure under monochromatic wave conditions.
