Analysis of double-row piles in consideration of the pile-soil interaction

Based on the current model of calculating double row piles, the new plane finite element model considering the pile soil interaction was presented in this paper. Soil between double row piles was regarded as a thin compressible layer and was simulated by a series of horizontal rings connecting the double row piles,so that the effects of the change of soil profile, compressibility and the treatment of soil between double row piles on the interaction between the double row piles could be considered in the analysis with no supposition of the sharing of total soil pressure between double row piles needed. The calculated results of the interaction of double row piles of an actual engineering project by the presented model showed that satisfactory result can be obtained with reasonable parameters applied in the model.
