( 4 ) in the interaction analysis of pile ? at foundation , the shear ? eformationed method which only deal with a single pile in homogeneous body previously has been developed so that the interaction analysis of piles with layer soil has been completed successfully . based on the flexible coefficient of the single pile , that coefficient of pile ? ile , pile ? oil or soil ? ile has been deduced , then rigid matrix of system of piles and layer soil can be gained
（ 4 ）在桩土共同作用分析中，本文发展了计算单桩沉降的剪切位移法，在得到单桩位移柔度系数的基础上，进一步得到了桩?桩相互作用位移柔度系数和桩?土相互作用位移柔度系数，从而得到了桩?土体系的刚度矩阵，使之可用于进行层状地基中群桩与土的共同作用分析。
