Experiment on influence of uniaxial tension on permeability characteristics of soil-geotextile system
In order to explore the influence of uniaxial tension on the permeability of soil-geotextile system,three kinds of woven geotextiles of the same type and three different specifications were selected.The constant head permeameter was used to conduct constant head permeability tests on three different specifications of geotextiles with warp and weft tensile strains of 0%,3%,6%and 9%,and the influence of uniaxial tension on the permeability of four kinds of geotextiles was analyzed.The results show that the permeability coefficient of soil-geotextile system shows a trend of decreasing first and then increasing when the geotextiles of different specifications are stretched in the warp direction.When subjected to weft tension,the permeability coefficient of the soil-geotextile system increases continuously and there is no final stable value.
