Geotextile tubes are tubes formed with geotextile and filled with the sand slurry. They are now popularly used in the coastal protection, river embankment construction and dewatering of the sludge/reservoir sediments. The stability of these structure under static loading condition are reported in the literature. However, their performance under earthquake condition is not well understood. In this paper, stability of stacked geotextile tubes under seismic loading are analyzed using a commercially available finite-element analysis software. The analysis considers two case scenarios: (1) geotextile tube stacking on ground base foundation; (2) geotextile tube stacking on gravel bedding foundation. The geotextile tube is modeled as membrane with negligible weight and extensibility. The effect of peak ground acceleration on the factor of safety is studied for different fill material and filling ratio. The performance of the geotextile tube with respective deformation and settlement are recorded for different diameter and the size of the tubes are optimized. The geotubes stacked over gravel bedding foundation performed better than that are stacked over base foundation. The present paper advances the scientific understanding of geotube embankment and would provide valuable guidance to the practitioner in the construction of resilient and sustainable embankment in seismic-prone zones .
