초록
기존 케이슨의 안정성을 높이기 위해 신규 케이슨을 기존 케이슨 전면 또는 후면에 추가로 설치하여 보강 하는 설계 및 시공사례가 발생되고 있다. 본 연구에서는 고유함수전개법을 이용하여 원형케이슨으로 구성된 기존 방 파제 후면에 신규 원형케이슨이 설치될 경우 각 원형케이슨에 작용하는 파력특성을 분석하였다. 수치해석의 신뢰성 을 확보하기 위해 상용화 프로그램인 ANSYS AQWA의 수치 해석결과와 비교를 수행하였으며, 원형 케이슨 추가 설치에 따른 파와 구조물의 상호작용 영향을 고려하여 각 원형케이슨에 작용하는 파력을 산출하였다.
Abstract
In order to increse the stability of old caissons, the design and the construction are performed by installation of new caissons on the back of or on the front of old caissons. In this study, we use the eigenfunction expasnion method to analyze the characteristics of wave forces when new circular caissons are installed on the back of old caissons. The comparison of numerical results between eigenfunction expansion method and ANSYS AQWA is made and the wave force acting on each circular caisson is calculated by considering the wave-structure interaction effect.
