Abstract：Based on linear load deliver function to pile-side soil and pile-end soil, and considering influence of sharing load of the pile-side soil on load deliver law of piles, Using mechanics theory and approximate solution method-district method of differential equation, approximation analytical formulas of interaction for the flexible grouped piles and soil are derived under rigid cap. The maximal pile-side friction force of central pile show up in pile-end, the maximal pile-side friction force of edge pile and angle pile show up near pile-top, under rigid cap.The pile-top counter force of the angle pile is the biggest，the edge pile is the second，the central pile is the smallest. To verifying the reliability of the proposed method, the results of the model test are compared with the results in this paper. contrast snunciation; the proposed method has good precision.
