In this paper, The stability of slope of the embankment reinforced with spun-bond non-woven fabrics under the effect of a seepage flow caused rainfall and the practical application of stability analysis are discussed, using the results of large-scale model test.The test varing the types of fill material and lengths and spacing of non-woven fabrics laid in the embankment were carried out. Their studies reveal that reinforced embankments are able to have high stability of slope under the heavy rainfall and the results of stability analysis based on the rational estimate of tensile strength of non-woven fabrics in the embankment coincide with those of model tests.
