• Behavior of Test Embankments Reinforced with Spun-bonded Non-woven Fabrics under Artificial Rain Condition

抄録

Large scale experiment on the behavior of test embankments reinforced with spun-bonded non-woven fabrics were carried out under artificial condition in order to investigate the erosion protection function of the fabrics. Test embankments were constructed using silty sand and have a height of 2.75m and solope ratio of 1:1.0. One of them was non-reinforced and the others were reinforced with fabrics, having a spacing of 60cm and 30cm respectively. Total cumulative rain fall was 453mm.<br>Acording to the test results, spun-bonded non-woven fabrics have an remarcable function of restraining erosion which proceed from the toe of the embankments and have another dintinguished function of draining seepage water through them and delaying the speed of strength reduction of the fill materials due to the increase of water content of them. And the denser the spacing of the fabrics, the more effective they are.
