Abstract

Abstract

Based on the finite element program ADINA,a 3D finite element study considering the boundary condition and the contact condition is used to determine the pile-soil-pile interaction behaviour for closely spaced square passive pile rows.The mechanism of soil arching,the relation of the pile deflection and the surface load,the soil pressure of the side of pile and the axial force are studied.It is shown that the nonlinear relation between the pile deflection and the surface load can be modeled by three broken model. The earth pressure on the side of pile is smaller than the Rankine passive pressure and larger than the Rankine active pressure.The ultimate pressure on the piles in the same soil shows linear and smaller than that by the Ito theory and the Shen Zhujiang's theory.
