Laboratory studies on geotextile filters as used in geotextile tube dewatering

Design method for geotextile tubes considering strain – Formulation and verification by laboratory tests using photogrammetry

“…Geosynthetic containers have been increasingly used in hydraulic engineering (Alvarez et al, 2007;Shin and Oh, 2007;Saathoff et al, 2007;Yan and Chu, 2010) and sludge dewatering (Koerner and Koerner, 2006;Muthukumaran and Ilamparuthi, 2006) projects during the past two decades. They come in a large variety of shapes and sizes, starting from simple sandbags to large tubes of more than 100 m in length.…”

The influence of uniaxial tensile strain on the pore size and filtration characteristics of geotextiles

“…The monitoring results from a geotextile-reinforced containment dike constructed on soft soil deposits by Schimelfenyg et al (1990) displayed that the strains in both the warp and fill directions were greater than 7%. In recent years, geotextile tubes/geotextile containers have been applied to engineering practice (Pilarczyk, 2000;Moo-Young and Tucker, 2002;MooYoung et al, 2002;Koerner and Koerner, 2006;Muthukumaran and Ilamparuthi, 2006).The geotextile tube is filled with liquefied soil or dredged materials by hydraulic pumping, allowing liquid discharge but retaining most of the solid particles. The opening size of the fabric being considered is important in successfully dewatering the dredged sediment.…”

Effect of deformations on the hydraulic stability of coastal structures made of geotextile sand containers

“…Geotextile sand containers (Koerner and Koerner, 2006;Muthukumaran and Ilamparuthi, 2006;Heerten, 1984) are now used for a wide range of applications. The hydraulic stability of geotextile sand containers (GSCs) subject to wave action has been studied within an ongoing extensive research program at LeichtweiX Institute on the use of geotextile structures for coastal structures, including artificial reefs, revetments, sea walls as well as dune reinforcement Oumeraci, 2005a,b, 2006).…”
