        우리나라가 세계 물류기지의 중심 국으로 발전하기 위해서는 날로 급증하고 있는 물류량을 처리하기 위한 항만의 건성이 시급한 과제이다. 국토가 좁고 대도기에 인구가 급증하고 있으나 삼면이 바라도 둘러 쌓여 잇는 우리나라의 경우에는 해양공간개발이 필요하다. 증가하는 물류량은 처리할 수 있는 항만의 건설을 위하여 본 연구에서는 초대형 부유채식 컨테이너 야드를 제안하고 해상에 설치되는 초대형 부유채식 컨테이너 야드가 파의 길이 , 해역의 수심, 입사하는 파의 방향등에 따라서 어떠한 응답특성을 나타내는지 파악한다.

        In the country where the population concentrates in the metropolis with the narrow land, development of the ocean space is necessary. Recently, mega-float offshore structure has been studied as one of the effective utilization of the ocean space. And very large floating structures are now being considered for various applications such as floating airports, offshore cities and so on. This very large structure is relatively flexible compared with real floating structures like large ships. when we estimate dynamic responses of these structures in waves, the elastic deformation is important, because vertical dimension is small compared with horizontal. And it is necessary to examine the effect of ocean wave external force received from the natural environment. In this study, the mat-type large floating structure is made to be analytical model. And the analysis of the dynamic response as it receives regular wave is studied. The finite element method is used in the analysis of structural section of this model. And the analysis is carried out using the boundary element method in the fluid division. The validity of analysis method is verified in comparison with the experimental result in the Japan Ministry of Transport Ship Research Institution. In order to know the characteristics of the dynamic response of the large floating structures, effects of wavelength, bending rigidity of the structure, water depth, and wave direction on dynamic response of the floating structure are studied by use of numerical calculation.
