摘　　要：分析了桩的荷载传递机理及桩侧极限摩阻力沿桩身的分布模式,并用荷载传递函数解析法定性分析了桩长、桩径和桩的刚度对粘土层中桩的极限承载力的发挥的影响。load-transfer menchanism of a pile and distributed mode of laterally limited frictonal resistence along a pile are analyzed.pile length 、diameter and Stiffness of a pile are qualitatively studied for their effect on the utilization of the ulitimate bearing capacity of piles with analytic solution of a load-transfer function.

关 键 词：桩 极限承载力 荷载传递
