摘　　要：分析了低承台复合桩基在竖向荷载作用下承台分担荷载作用、承台底土的强度和承台尺寸,以及桩长对分担作用的影响,从而得出承台不但本身可承担荷载,且承台的效应可提高桩基承载力,亦有节约资金之潜力.This paper is analyzed the effect of capping share loading function,soil strength,capping dimension and length of pile for share function under axial loading.It can be proved that the pile capping not only could share loading by itself but the effect fo pile capping also can improve the bearing capacity of high pile foundation and really have the potentiality of saving the capital.

关 键 词：承台效应 土反力 桩基承载力
