ABSTRACT. Most of the current criterions of the pile foundation design are only concerned with the pile capacity, the vertical and horizontal displacements of the pile, but not attended to the stability of the pile. For instance, the stability of the driven piles in construction stage. In this study, the two most common types of piles, square and prestressed circular piles, were considered. The three dangerous construction phases which is the large threat to stability of the pile were simulated. Analysis progress was performed with the analytical method and finite element method. The results were verified with the actual pressure to evaluate the safety of the pile during construction.
