BACKGROUND: In the early 1990s, some U.S. Army Corps of Engineers Districts began using and evaluating custom-made geotextile tubes with fabric tensile strengths ranging between 400 and 1,000 lb/in. (70,000-175,000 N/m). The tubes have been used as containment dikes for dredged material placed in shallow water to intertidal elevations. Wetlands have been restored on the dredged material with th...

The paper presents the effect of using cashew nut shell liquid (CNSL), a low-priced agro by-product and renewable resource, to treat coir geotextiles. Large-scale direct shear tests were performed on sands reinforced with untreated treated geotextiles at different normal stresses (50 kPa, 100 150 kPa). Sands three particle sizes (coarse, medium, fine) used for study. strength parameters soil sa...

Purpose: To investigate the roadbed in construction of pile foundation united by flexible grillage made geosynthetic material. how material will work such a grillage. create analytical model with determine strength textile used construction. analyze advantages and flaws existing methods for calculating structure Methods: Structure parameters reinforced material, were calculated using three meth...

The results of the study nature work reinforced foundation pads from cohesive soil. Compacted soft-plastic loam is considered as pad material, woven geotextile used a reinforcing element. Such constructive solution pad, rule, associated with impossibility or high cost using classical inert materials for these structures. Previous studies have shown efficiency rational arrangement horizontal geo...

Sources of contamination in a subsurface environment are petrol, diesel fuel, gasoline at oil refineries, underground storage tanks, transmission pipelines, and different industries. The permeable reactive barrier (PRB) is promising technology to remediate groundwater in-situ. In this study, synthetic samples containing toluene treated three reactor columns by biological processes. PRB-1 consis...
