根据Mindlin基本位移解提出了一个群桩中的单桩的位移函数关系式，运用变分理论和最小势能原理，结合Randolph的单桩位移解法中的桩周土体剪应力和位移关系，桩端土与桩端沉降关系进行推导，得到了群桩中单桩的荷载位移关系，并以实例与他人结果进行对比。对比结果表明：本文提出的方法计算得到的结果与用其他方法得到的结果一致。

Based on Mindlin basic displacement solution , a function of the displacement of single pile in pile group was presented using the variation theory and the principle of minimum potential energy .Combined the relationship between shear stress and displacement of soil around pile in Randolph single pile displacement solu -tion and the settlement of pile bottom , the single pile in pile group of load -displacement relationship was de-rived.Compared with the results of others , the results show that the proposed method is close to other methods .
