A Method of Calculation on the Deformation of Column Piles in Deep Foundation Pit

Abstract:

During excavation of deep foundation pits, the effects of vertical deformation on column piles are often neglected while those uplifts may lead to destruction of internal supports. The factors leading to the column piles' vertical deformation mainly include basal uplift and vertical loads. In this paper, the causation and mechanism of the column piles' uplift are discussed. The influence of the additional bending moment due to the column piles' vertical deformation on the overall stability of the founda-tion pit is analyzed. A calculation method of the permissible value of vertical deformation is present¬ed. The method is verified by a practical case to be feasible.
