摘要
通过分析桩－土－垫层的共同作用，讨论了刚桩复合地基的工程特性，推导出在荷载作用下，当桩端土层为文克勒地基时的桩顶荷载、土体表面荷载、柱体沉降、土体沉降、受荷后垫层厚度等的计算公式，并根据推导出的应力比公式对应力比的多种影响因素进行了探讨。
With analysis of cooperation of piles, soil and cushion, working performace of the rigid pile composite foundation is dis- cussed. By the equations presented in this paper, load distribution and settlement of foundation can be calculated. Equation to calculate the stress ratio is obtained and factors that influence the stress ratio are thereby discussed.
