Design Method for Flat Geotextile Tubes filled with Inhomogeneous Slurry
The circumference tensile force developed in the geotextile during filling the tube is the dominant factor to construct a safe dike. Based on the feature of flat tubes, a iterative procedure is programmed, with which the shape of the large size geotextile tube, as well as the relationship among the tube size, the pumping pressure, the unit weight of the slurry and the tensile stress developed in the geotextile during filing the tube can be determined. In the procedure, the inhomogeneousness induced by the soil grain sedimentation is also considered.
