Model Test of Stacked Permeable Geosynthetic Tubes
Geosynthetic tubes made of woven geosynthetic material provide an ideal medium for the dewatering of digested bio-solids, dredged materials and industrial solid wastes and for the construction of levees. However, the dewatering process of a single permeable geosynthetic tube is time consuming. A better way is to stack permeable geosynthetic tubes one layer on top of another to use the weight of the tubes as surcharge. In order to improve the understanding of the performance of stacked permeable geosynthetic tubes, model tests of stacked permeable geosynthetic tubes resting on rigid foundation were carried out. A 2.0-mm-thick woven polypropylene geosynthetic sheet was used for the geosynthetic tubes. The deformation of the 2-layer geosynthetic tubes versus time curves are presented and analyzed in this paper. The time taken to achieve 80% dewatering efficiency for the stacking method is only 38% of that for the single tube method.
