Abstract

Geotextile tubes are manufactured by woven or geocomposite geotextiles to form tubes that are later filled with high-water content materials by hydraulic pumping. When geotextile tubes are used in dewatering slurries, a filer cake forms on the interface of the soil and geotextile. The formation of the filter cake, which leads to the retention of the soil particles, can be controlled by the pore openings of the goetextile, the particle size distribution of the soil, the water content of slurry, and the confining pressure. In this paper the results of pressure filtration tests on Cayuga Lake sediments using four geotextiles are presented. The influence of geotextile manufacturing processes, pore opening, water content, and confining pressure on filtration behavior are discussed. Copyright ASCE 2006.
