| 摘 要： | 地基、基础与上部结构共同作用近年来成为理论研究与工程实践的热点问题。根据三者之间的相互作用原理，将地基基础与上部结构作为一个整体进行研究，通过选用合适的三维空间计算模型，考虑了材料的非线性和边界条件的非线性，应用数值仿真系统ANSYS程序对所建模型进行模拟分析。对于软硬不同的地基模型，计算结果表明，不同硬度的地基会在上部结构及基础中产生应力重分布，同时还得出了地基土应力的空间分布规律，此结果具有一定的理论和应用意义。

| Abstract: | The subject of interaction between foundation-subsoil and superstructure has become a new and hot application subject in recent years. In this paper, the foundation-subsoil and superstructure is studied based on the theory of the interaction between them. By choosing appropriate three-dimensional mechanical models, finite-element program "ANSYS" is used to calculate and analyze these models. In the method of simulation, material nonlinear and boundary nonlinear are considered. As for soft hard different foundation models, the result of calculation indicates that different hardness foundation will produce the stress distribution in upper structure and foundation again. At the same time, the diversification regularity of subsoil internal stresses is obtained. This result has its theoretical and applied values. |
