geotextiles are one of the most widely used synthetic materials in filtration and drainage applications. since in real applications, geotextiles are subjected to various hydraulic gradients and confining stresses, hydraulic behavior of geotextiles under different circumstances is of great practical importance. in this study filtration and drainage properties of several nonwoven needle-punched g...

conventional investigations on the behavior of reinforced and unreinforced soils are often investigated at the failure point. in this paper, a new concept of comparison of the behavior of reinforced and unreinforced soil by estimating the strength and strength ratio (deviatoric stress of reinforced sample to unreinforced sample) at various strain levels is proposed. a comprehensive set of labor...

Characterization of a geosynthetic is necessary for its effective use in various field application of reinforced soil structure. In this paper, a new type of geosynthetic has been evaluated for its interaction properties for different backfill soils using direct shear device. The test results are compared based on the type of soils, inclusions, and interface mechanical properties. Three backfil...

Natural fibres such as jute were the forerunners of the man-made fibres used for centuries for making ropes and formanufacturing burlaps, sacks, hessian and carpet backing. But the use of jute products in civil engineering is relativelywidespread for such purposes as sand-bags for concrete curing, soil enrichment and protection. This research is concerned with the stabilization of fine sand usi...

Geotextile is one of the reinforcement materials adopted in many engineering structures. Conventional geotextiles have a limited effect due to insufficient friction strength between and soils. This paper proposes novel type geotextile with stitched transverse ribs improve effect. A series large-scale direct shear tests been conducted, improvement characteristics conventional geotextiles, geogri...

The ground in Saemangeum has a high water level and is mostly composed of silty soil sand, which makes it susceptible to liquefaction seepage effects. To investigate the seismic response geotextile tube-reinforced embankment shallow foundations laid on liquefiable soil, simple spring type shaking table apparatus was developed. variation acceleration shear stress-strain relationship were investi...
