Geotextile tubes provide a quick and potentially cost-effective solution for dewatering.
Use of geotextile tubes causes less impact on the environment for dewatering contaminated materials, because the slurry-like materials are contained in the tubes during the process. In some cases, geotextile tubes need to be stacked in multiple layers because of limited site footprint. A parametric study was carried out to evaluate the slope stability of stacked geotextile tubes. Results of the study are presented in this paper as slope stability charts. These charts can be used to quickly evaluate the feasibility of a project that involves stacked geotextile tubes with regard to geotechnical slope stability.
