Analysis of piles reinforced effects on interaction coefficients of piles

The interaction coefficients of pile group were usually analyzed with plane strain model, which had too many assumptions. Based on a more rigorous model of imaginary piles, integral equation approach for piles group interaction was applied to analyze the effects of piles reinforcement in soil. To simplify the analysis, two piles model was given. Compared with the elastic theory method and Mylonakis & Gazetas method, it shows that the effects of piles reinforcement in soil had obvious influence on the interaction coefficients of pile group. Finally, some defects of Mylonakis & Gazetas method based on the shear force-displacement model are pointed out.
