Abstract

The problem of critical length of pile in composite foundation is studied by means of FEM analysis in which the loads are exerted separately on a single flexible pile,large area of flexible piles group and flexible piles group under road embankment.The conclusion is reached that the critical length of pile in composite foundation is related not only to the modular ratio of pile /soil but also to the load distribution.
