Abstract In order to have an in-depth study of the filling property of geotextile tube，based on the indoor model filling experiment，the shape，height，tension，the bottom pressure acting on the bag and the drainage rate of the tube are tested. The test data could provide verification for theoretical study. The results show that：as the filling proceeds，the height of the tube is increasing rapidly；and the other characters such as the tension，the bottom pressure，the drainage rate grow with it quickly；when the drainage rate grows close to the filling speed，the speed of increase in the height of tube is reduced significantly. The height of the tube，which is determined by the filling pressure and the permeability of the geotextile，could be controlled by the filling speed after the suitable geotextile is chose. The drainage mainly occurs in the filling process and within a few minutes after the completion of the filling. The cross-section of the tube is oval arc shaped，which could be dealt with as the plane strain problem.
