Abstract

  Two dimensional tank experiments were carried out in order to decide the size and design of geotextile structures that were planned to be constructed on the Seisho coast, Kanagawa, Japan. Under the high-wave condition, 1/30 scale models of the geotextile structures were less stable than traditional concrete blocks with the same weights. Geotextile structures whose weights were more than 10 times those of concrete blocks proved to be stable against wave attacks. The typical deformations of geotextile structures, such as the uplifting of the tip of the structures and sideward twisting of the structures, were observed. The experimental results indicated that the deformations could be effectively prevented by modifying the shape of the structures by increasing their width and height. One mass coastal geotextile structure with a width of more than 8 m, length of more than 15 m, height of more than 1.5 m that could endure the highest waves observed in the Seisho coast in the last 15 years was proposed.
