Loading Test of Model Embankment Reinforced with a Nonwoven Fabric

Abstract

For the purpose of making clear the effectiveness of reinforcement of embankment using a nonwoven fabric as a tensile-reinforcing material, loading model tests were conducted.
We made a reinforced Kanto Loam embankment, having a steep slope inclined at an angle of 73°, by laying nonwoven fabrics horizontaiiy and rolling up along the embankment slope.
We carried out two cases of loading tests, for embankment reinforced with a nonwoven fabric and unreinforced embankment.
The results of these tests may be summarized as follows;
a) Local collapse of slope can be prevented by reinforcing embankment with a nonwoven fabric.
b) Yield load of reinforced embankment is about 3.6 times as large as that of unreinfored embankment (for Kanto Loam of Cohesion: C=0.1kgf/cm², Internal friction angle: φ=10°).
