| 摘 要： | 结合一个桩筏联合基础的设计过程,探讨了在复杂地基土上基础设计中的受力分析及变形协调计算过程.介绍了在满足复合地基承载力和变形要求前提下合理布置桩筏联合基础的做法及其设计思路.布置桩筏联合基础时使桩筏分别落在不同土层上,以充分利用不同深度地基土的承载力;另外针对桩下为非淤泥系硬土层,应最大限度利用桩身强度和天然地基承载力.该做法可以取得很好的经济效益,可供工程设计人员参考.

| Abstract: | In order to make full use of the loading capacity of foundation soil, to increase the loading capacity of compound foundation soil and save the foundation engineering cost, the authors have tried on a transnormal design on the existing foundation standards according to engineering characteristics. The pile-balsa is reasonably arranged in the foundation. Thus the piles and balsa will be located at different soil layers, meeting the requirements of codes on the compound foundation loading capacity and deformation. This design shows that the pile-balsa compound foundation in certain geologic conditions is an effective way to save cost. |
