Abstract  The filling construction of permeable geosynthetic tubes is considered. First, an analytical approach is developed to determine the internal pressure, tension and shape of the cross section of a geosynthetic tube based on its volume. An analytical solution for the drainage rate of the tube is then derived. The course of the filling construction is divided into several time intervals and the volume of the tube after each interval is obtained from the equilibrium of flow calculated from the drainage rate and filling rate. The validity of our analytical approach is tested by comparing our results with previously published experimental result. The results of this comparison indicate that our method is applicable for simulating the filling construction of permeable geosynthetic tubes.

Key words： Geosynthetic tube      Filling construction      Simulation      Volume of the tube      Drainage rate
