ABSTRACT

This study is experimental research according to sand injection about the deformation and debris yield characteristics of geotextile tube which is focused as an alternative prevention method of beach erosion recently. Model of 1/40 scale to prototype was made to analyze the behavior of geotextile tube according to filling rate. At the beginning of experiment, stress deformation was increased at the upper tube when the sand was deposited at the bottom of tube. Load was uniformly distributed and the rate of coarse particle was high when the filling rate was low at the beginning of experiment. However, rate of fine particle was high when the filling rate was high. Furthermore, it was found that stress deformation was occurred at the bottom of tube from the beginning of filling. Bottom of tube was settled and compress deformation was occurred when the amount of filling sand was increased.
