In-Plane Hydraulic Properties of Geotextiles
註釋Because of the large number of practical applications using the in-plane hydraulic properties of bulky geotextiles, there exists a need for a suitable test method, which should eventually be standardized. The method developed here measures the parallel flow of water in a constant head device using relatively large rectangular specimens measuring 61.0 by 30.6 cm (24 by 12 in.). The device can support normal stresses on the geotextile up to approximately 144 kPa (3000 lb/ft2).
