MODEL TESTS ON A GEOSYNTHETIC REINFORCED SAND REVETMENT SUBJECTED TO ASSAILING WAVES

Abstract

The behavior of a Geosynthetic reinforced sand revetment (GRSR) is simulated using a “wave-maker tank”. The GRSR is built inside the “wave maker tank” and is subjected to different kinds of simulated traveling ocean waves. It consists of four-layers of wrap around geosynthetic filled by Toyoura sand. Two kinds of GRSR were analyzed, one reinforced with a geocomposite and the second with a non-woven geotextile. Loose and dense sand were used, lateral and vertical deformations as well as density changes due to wave action were measured. Results from these model tests regarding relations among wave action-deformation, time dependent patterns, influence of wave height, collapse mechanism as well as the influence of the foundation are presented in this paper.
