A series of laboratory model tests on embankment were performed to investigate the method of improving the structural stability of soil structure that was constructed upon slope against rainfall. The effects of the amount of rainwater flowing into the embankment from the natural ground and the surrounding on the stability of soil structures were focused in the present study. As the results of model tests, the stability of the embankment upon slope depends on the amount of seepage pressure at toe of the slope. In the present study, it was confirmed that soil-reinforcement by using geosynthetics with counterweight for the toe and drainage is effective for improvement of structural stability of soil structure against rainfall. The geosynthetic-reinforcing is also effective against erosion due to surface water.
