초록

오늘날의 정보통신시대에 있어서는 대용량의 정보를 전달할 수 있는 해저광케이블의 역할이 더욱 중하나 열악한 해양환경에 놓여 있어 설치시나 운용시에 파손의 가능성이 높으며 파손시 막대한 손실을 초래한다. 본 연구에서는 해저케이블 해석에 적용되는 여러 수치기법중 유한차분법에 근거하여 포설시뮬레이션 프로그램을 개발하였으며 케이블 포설시의 2차원 동적거동해석을 수행하였다. 여러 경우에 대한 예제해석을 수행한 결과 프로그램에 의한 계산 결과가 만족스러운 것으로 확인되었으며 케이블에 대한 직선형상이론을 적용한 결과와도 잘 일치하였다.

Subsea cable systems have a large information transmission capacity and play an important role in domestic and global information networks. However since the cables are under harsh marine environment, they are exposed to various hazards with high potential risks of damage resulting in serious economic loss. In this research a computer simulation program based on the finite difference algorithm was developed. The program is able to simulate two dimensional dynamic behaviour of a submarine cable during its laying. In order to verify the numerical results, they are compared to analytical results, showing a good agreement between the two results.
