Abstract
The factors affecting the vertical loads acting on embankment piles can be classified into two factors on pile and soil. Factor on pile is the space between pile cap and factors on soil are embankment height and soil parameters(c, $\phi$). Therefore, a series of model tests were performed both to investigate the extent of influence of these factors and to verify the reliability of the proposed theoretical analysis. In the model tests, the piles were installed in the 6 columns $\times$ 6 rows(or 5 columns $\times$ 5 rows) below the embankment and the isolated pile caps with the area of 2.5cm $\times$ 2.5cm were installed on each pile head. The portion of the embankment load carried by model pile caps decreases with increment of the space between pile caps and increases with increment of the embankment height and the relative density(or internal friction angle) of fill. Also, the experimental results showed good agreement with theoretical predictions.
