上部结构、拱式基础与土共同作用分析研究

Analysis of interaction of superstructure,arch-foundation and soil

建立了一种拱式基础、上部结构以及地基土共同作用的数值分析方法。为了考虑土的层状分布及非均质性 ,提出了有限层子域法 ,对拱式基础中承台板 ,离散成带旋转自由度的组合厚板单元。编制了计算程序 ,对一已建建筑的拱式基础进行了分析 ,并将结果与常规基础设计理论作比较 ,获得了一些对拱式基础设计有益的结论。

An approach was established for the numerical analysis of the interaction among superstructure, arch foundation and soil. In order to consider the effect of multi layered ,non nomogeneous soil, subdivision finite layer method was presented. Pile cap was divided into assembling thick plate elements with rotational D.O.F. An existing construction with arch foundation was analyzed and some interesting results were obtained which may be useful for practical design.
