摘　　要：我国《动力机器基础设计规范》(GB50 0 4 0 96 )确定桩的竖向刚度时采用刚性桩的设计理论。对桩土体系采用多质点离散化模型对桩的刚度进行了分析 ,指出 ,按刚性桩的计算结果过于偏大 。The theory of absolutely rigid pile is adopted in the Code for Design of Dynamic Machine Foundation in China.The stiffness problem of pile is discussed in this paper under the condition of adopting multi\|mass system.The paper shows that the computation results of rigid pile are obviously greater than deformation pile and the non\|uniform distribution of pile\|side stiffness along the pile will also markedly effect the pile stiffness.

关 键 词：桩侧刚度 桩尖刚度 刚性桩 变形桩
