本文考虑上部结构、基础和土的共同工作,用有限单元法计算基底反力和基础内力,计算时将上部结构、基础和土考虑为一个统一的整体,并可根据结构的实际情况划分单元,又可考虑地基土的层向结构分布和土的非匀质性。文中以保定冷库为例进行了计算,所得结果与实测十分接近。
This paper considers the joint work of the superstructure, foundation and soil, and calculates the base reaction force and the basic internal force using the finite element method. When calculating, the superstructure, foundation and soil are considered as a unified whole, and the unit can be divided according to the actual conditions of the structure. The layered structure distribution of soil and the heterogeneity of soil can also be considered. In this paper, Baoding cold storage is calculated as an example, and the results are very close to the actual measurements.
