Construction and Monitoring of Geotubes

摘要

Geotubes are made from permeable, soil-tight geotextiles that are filledwith dredged soil. The performance of pilot scale field tests using ageotube is presented. The geotube was made from a woven geotextile.It was filled by hydraulically pumping dredged silty clay material intoit. The variations of the shape of the geotube and the dry unit weight,moisture content, and vane shear strength of the soil at various locationsin the geotube with time are summarized. Based on this study, itappears that geotubes are feasible construction materials for use incoastal engineering projects.
