Geotextile Tube technology research was first conducted at the Delft Institute in the Netherlands in the 1970s, it was applied for the first time in Brazil in the 1980s. In recent years, faced with emerging environmental issues under extraction of riprap and under the condition that riprap materials can’t be easily be obtained, geotextile tubes method are applied as an alternative solution. (Kim et al, 2014) Both domestic and abroad, the construction of geotextile tubes is presently increasing, particularly applied as facilities like temporary dike and coastal erosion control structures. However, there is still a few research conducted on the permeability of geotextile tubes filled with dredged material. Under this background, the purpose of this study is to analyze the permeability of geotextile tubes filled dredged soil depending on the seepage pressure.

Geotextile tubes are water-permeable tubular structures made of woven polymeric polyester (PET) or polypropylene (PP) synthetic fibers hydraulically filled with dredged sand currently used as alternatives for embankment construction. In this paper, a large direct-shear test was performed on a soil sample with wooden block wrapped by geotextile to figure out shear property of soil-geotextile tube interface.

A stilbene glucoside was isolated from the methanol extract of Polygonum multiflorum and its structure was determined based on the spectroscopic method. This stilbene glucoside showed comparable antioxygenic activity with ascorbic acid and BHA which are currently being used in the market.
