Abstract: Base on the elastic foundation beam model in the foundation work, the differential relationship of the load-internal force-deformation of the piles is established. Each pile component of the multi rows of the piles is divided into a group of bars according to different differential equation. A differential equation is established for each bar, and all the equations are integrated into a differential equation set. The internal force and deformation of the multiple rows of piles are obtained according to the boundary condition, the deformation compatibility of the bar node and the balance conditions of the internal force. Case study is carried out and the results verify the feasibility of the proposed method for internal force analysis of multiple rows of piles.

Key words: engineering mechanics, multiple rows of piles, differential equation set, internal force analysis
