Some issues of design-implementation and application of Geotube

Abstract

     A Geotube is a tube made of permeable but soiltight geotextile and filled with sand or dredged material. Its diameter and length are specific for each project and are limited by installation possibilities and site conditions only. In the world, geotube was used popularly for protection works but in Vietnam, it is limited applications. This paper has the major design considerations include sufficient geotextile and seam strength in order to resist pressures during filling and during impact of geocontainer on the bottom and compatibility between fabric and soil, analyses economic, advantage and disadvantage of geotube. Research results will be applied for Vietnam standard design of sea dike overtopping.
