Abstract

A large scale hydrological laboratory model tests for the geotextile tube were conducted to investigate the stability of geotextile tube and the capability of breakwater with variations of significant wave height, percentage of soil filling, and the water level above geotextile tube. The sliding displacement of geotextile tube is measured to check the stability of geotextile tube for given the various significant wane heights. The marked mash was laid out at the bottom of water channel to measure the displacement of geotextile tube. The bench mark was furnished in the upper part of water channel and the initial location was marked every 10cm interval to measure the displacement of geotextile tube. The wane transmit ratios are analyzed with the variations of soil filling of tube and of the top crown height wave above the geotextile tube in order to study the performance of brekwater before and after the installation of geotextile tube.

본 연구에서는 유의파고별, 지오 튜브의 채움비, 지오 튜브 천단고의 변화에 따라 지오 튜브의 안정 및 소파성능에 관한 실험을 실시하였다. 축척은 1/50로 하여 조파 수로내에 모형을 설치하였다. 안정성 시험은 유의파고를 재현하여 지오 튜브의 변위를 계측하여 검토하였다. 지오 튜브의 각 부분의 변위량을 관찰하기 위하여 바닥에 메쉬를 설치하여 계측하였으며 지오 튜브 상부에 기준선을 표시하고 10cm 간격으로 초기 위치점을 설정하여 계측하였다. 소파성능은 지오 튜브의 설치전과 설치후의 각각의 채움비에 따라 천단고가 있는 경우와 없는 경우 파고전달율 해석하여 비교 분석하였다.
