초록

본 연구에서는 육상구조물에 작용하는 지진해일파력해석을 위하여 Navier-Stokes slover에 기초한 3차원 혼상류수치해석법을 적용하여 검토하였다. 여기서, 대상구조물을 육상저유탱크와 육상가옥으로 하여 호안과 육상구조물간의 이격거리에 따라 육상구조물에 작용하는 지진해일파력을 검토하였다. 또한 육상구조물에 작용하는 지진해일 파력의 추정을 위하여 항력만을 고려한 방법과 항력 및 관성력을 동시에 고려한 방법을 각각 적용하여 얻은 결과와 수치해석결과 및 설계기준에 의한 결과치를 비교 분석하였다. 이로부터 항력 및 관성력을 동시에 고려하여 추정한 지진해일파력이 항력만을 고려한 경우 보다 수치해석결과에 더 근접하는 것을 확인하였다.

This study investigated the tsunami force acting on onshore structures using a numerical program, three-dimensional one-field model for immiscible multi-phase flows, which is based on Navier-Stokes solver. In this paper, the characteristics of tsunami of oil storage tank and house structures studied to the distance between the seawall and structure. In addition, the study compared and analyzed the tsunami forces determined by considering drag force only and considering both drag and inertia forces. These numerical results were compared with the design standard. As a results, the case of considering the both forces is more close to numerical result than that of considering the drag force only.
