Monitoring of Strain Behaviour of Geotextile Tubes under Wave Load in Hydraulic Wave Flume
Monitoring of Strain Behaviour of Geotextile Tubes under Wave Load in Hydraulic Wave Flume
Geosynthetic containers, such as geotextile bags and geotextile tubes, have been widely used in hydraulic and coastal engineering applications. While many studies have focused on the structure stability of these systems under various field scenarios with wave action, limited research has addressed the strain behavior of the geotextile sheet that made up the tubes under such action. This study aims to investigate the mechanical response of geotextile tube, and the strain development of the geotextile sheet under wave loading through a series of physical model tests. The experiments will be conducted in the 36 m long, 2 m width Ferrocement Flume at the National University of Singapore. A custom-made geotextile tubes made by non-woven geotextile was used in this study. To avoid the hydraulic scaling issue, the strong grade of typical geotextile used in the field (T 200 kN/m) was scaled down according to the wave load. Hence, a much weaker non-woven geotextile was selected to fullfil the scaling law. The strain behavior in both the longitudinal and transvese directions of the tube is monitored during pumping and wave loading stage. The results of this study will provide valuable insights into the material-level performance of geotextile tubes under wave action, offering a practical reference for the design and application of geotextile tubes in coastal and hydraulic engineering.
