The consolidation theory of granular column composite foundation can date back to the precious works of Carrillo [1] and Barron [2], in which the consolidation properties of a sand drain well foundation were theoretically analyzed.
Then, a closed-form solution for the consolidation process of a stone column composite foundation employed in the enforcement of expressway embankments is derived based on the basic idea of calculation method for a sand drain well foundation, which divides the consolidation problem into two parts, that is, radial consolidation part and vertical consolidation part.
To study the effectiveness of vertical drains, a trial embankment using vertical sand drain was constructed.
In this trial embankment, sand drain, which is an early application of vertical drain to accelerate consolidation of soft, is used.
