dc.description.abstract | This This study attempted to evaluate the stability of the protection methods by examining hydraulic characteristics of the area around the point in which marine cable protection is installed such as surf zone occurrence point of shallow water submarine cables suitable for coastal marine environmental conditions, flow rate the top of the protection, maximum wave height and to provide basic data for the selection of the optimal protection method. In performing hydraulic model tests, the topography of submarine cable installation location was reproduced in 2-D sectional channel, and models appropriate for experimental scale and similitude law were produced and installed for each condition of submarine cables and protections. For stability review, an experiment to examine the stability was conducted using a wave maker with 50-year frequency design waves as target. Wave height and wave periods were applied based on the approximate lowest low water level (Approx. L. L. W), which is the most dangerous in submarine cable protection methods. As for experimental time, typhoon passing time in summer (about 3 hours) was applied, and wave patterns and breakaway ratio of the submarine cable protection were investigated after making irregular waves corresponding to design waves. In addition, current meter and wave height meter were installed at the installation location of the submarine cable protection, and the velocity and wave height at the top of the protection were measured and analyzed to review hydraulic properties. The hydraulic model test results showed that the total average breakaway ratio was less than 3%in Case5 (FSB 12ton, 2-row diagonal unite) of non-excavation conditions, Case 6 (FSB 12ton, 2-row triangular unite), Case 9 (FCM, 2-row unite) and Case 4 (FSB 12ton, 1-row unite) of excavation conditions, and Case 8 (FCM, 1-row unite), indicating relatively stable maintenance. | - |
