Experimental Study of Flow Through Geotextiles

Abstract

Filtration flows through various geotextiles are experimentally studied using a laser Doppler velocimetry technique. Comparisons are presented of the hydraulic behavior of needle-punched and heat-bonded geotextiles, and some influences of fabric damage and flow regimes are demonstrated to characterize geotextile efficiency.

Comparative study between needlepunched nonwoven geotextile structures made from flax and polyester fibres

“…The design of a geotextile accounts for soil-geotextile interaction, internal stability of the soil, isotropic characteristics of the geotextile structure and flow conditions, i.e. seepage velocities and hydraulic gradients (Adanur and Liao, 1998;Adolphe et al, 1994;Elsharief and Lovell, 1996;Jeon et al, 2004;Kabeya et al, 1993;Liao et al, 1997;Mogahzy et al, 1994;Saidi et al, 1999;Villard and Giraud, 1998;Wei et al, 1985;Zhai et al, 1996). However, the selection of fibre and fabric types is of paramount importance for any geotextile-based application.…”

Evaluating the performance of geocells made from needle-punched nonwoven layers in the bearing capacity of reinforced soil

“…Many researchers have consistently performed experimental and theoretical studies to show the advantages of using fabric as geotextile and geocell in soil reinforcement (Adanur & Liao, 1998;Adolphe, Lopes, & Sigli, 1994;Hwang, Lu, & Lin, 1999;Liao, Adanur, & Drean, 1997;Mogahzy, Gowayed, & Elton, 1994). Mogahzy et al (1994) studied the effects of geotextile characteristics on soil-geotextile interaction.…”
