Durability Study for Geotextile Tube Use in Talimu River Sediment Control

Source

To rebuild dikes for Talimu River regulation project, insitu sediments is considered to be contained by geotextile tube ( geotube ) for use as dike core. Stress analysis and matrix shape analysis are required to determine the geotube size. Based on experience and the local climatic conditions of Xing Jiang, China, durability of the geotubes is considered the most critical factor for sediment control. The geotube material used in this study is woven geotextile made in Taiwan — GTM-1 and GTM-2. The tests were conducted in accordance with ASTM Test Method (D 4355) for deterioration of geotextiles from exposure to ultraviolet light and water. After UV exposure for 200 and 500 hours, the results showed that the residual tensile strengths of the geotextiles are greater than 90 % and 70 % of the ultimate tensile strength, respectively. More results showed that reduction in tensile strength is insignificant even after UV exposure for over 600 hours. Another durability test is the geotextile's resistance to freezing and freeze-thaw cycles. Initially the geotextiles were placed in a temperature chamber and cured at -20 °C, -30 °C, -40 °C for 6 days. The results showed that the geotextiles still retained greater than 90% of its ultimate tensile strength. For the freeze-thaw cycles (-40 °C–40 °C, -10 °C–20 °C), results also indicate that the selected geotextiles provide good freeze-thaw resistance.
