Abstract: In designing geotextile tubes, obtaining hydraulic compatibility between the geotextile and the filler material can be complex because the geotextile tubes performance is affected by many factors such as the filling pressure, soil properties, geotextile properties, foundation properties. Hybrid geotextile tubes, which are tubes composed of various geotextiles arranged circumferentially, were proposed by the authors to optimize their filling and dewatering performance. To assess the behavior of hybrid geotextile tubes during filling, a scale model test on hybrid geotextile bags during filling was conducted. Through the scale model test, the retention performance, filling time, and water pressure of four hybrid geotextile bags were evaluated. The results of the study show that the performance of geotextile tubes can be optimized in various ways by interchanging the geotextile placement, by changing the circumferential lengths of geotextiles, and using geotextiles with different properties.
