摘要

群桩相互作用系数通常是采用平面应变模型进行分析，其研究方法具有较多的近似性。基于更为严格的虚拟桩模型，应用群桩相互作用的积分方程解答，以两桩相互作用的基本模型为例，研究加筋效应对群桩相互作用的影响。与弹性理论法和Mylonakis & Gazetas解答的对比表明，加筋效应对群桩相互作用系数有着较为明显的影响，并指出Mylonakis & Gazetas基于剪切位移法所得解答中存在的一些主要问题。

Abstract

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.
