| 摘 要： | 从阐述复合地基与桩基之间的区别入手，通过对桩体刺入垫层的研究，寻找在桩头呈理想球形孔条件下，垫层、桩体、桩间土三者模量与刺入量之间的关系，进而讨论了在刺入模式下的加固区复合模量计算问题。还讨论了复合地基桩上材料最优发挥状态问题，力图寻找最佳的桩土荷载分担比。

| Abstract: | Proceeding from the analysis of the deformation caused by pile stab into cushion or substratum,this paper has discussed the relationship of the meduli of pile, cushion and soil with the stab, and revised the formula of compoSite modulus. Further more, this paper has discussed the problem of optimum state of two kind of material. And efforts have been made to get the optimum pile-soil foring ratio. |
