Behavior of Prototype Steep Slope Embankment having Soil-walls Reinforced by Continuous Threads

Large-scale model tests were carried out under artificial heavy rain conditions to study the behavior of 5m hight steep slope embankments having soil-walls reinforced by continuous threads. The erodability of the soil-walls and the stability of the embankments were examined.According to the test results, it was concluded that the soil-walls reinforced by continuous threads are highly resistant to erosion due to rain and that the stability of the embankment having soil-walls can be analyzed using circular slip method if soil-walls are thin, or conventional design method for concrete retaining walls if soil-walls are thick enough.
