| 摘 要： | 探讨了深厚软弱地基上多（高）层建筑桩基础的共同作用分析方法，建立了桩土相互作用的界面模型，采用子结构法考虑上部结构刚度对基础变形和地基沉降的影响，同时考虑地基为弹塑性的，并采用无限元法考虑远场区域的影响。通过一个工程实例验证了模型的合理性，计算结果表明，计算方法能反应深厚软弱地基上桩基础的沉降特性。

| Abstract: | This present paper deals with the interaction analysis method of pile foundation established on thick and soft groundsill. A contact interaction model is given to simulate the interaction between pile and soil, soil and base slab. As for the superstructure, it uses substructural method to take its stiffness into account to the settlement of foundation. It regards the soil as elasto-plasticity, and uses infinite element to account for the effect of far field groundsill. In the end, an analysis example is given. From the results, It can bee seen that the analysis method adopted in this paper works very well. |
