摘    要:随着山地城镇建设的发展,一些建筑不得不建于边坡地基之上,边坡地基与建筑结构之间的共同作用成为一个现实的研究课题。通过有限元数值分析的方法,对某框架结构及筏基与边坡地基的共同作用受力问题进行了计算分析,其中边坡地基坡高10m,坡度为2:1,上部建筑为10层的框架结构。共同作用分析中上部结构、基础与边坡地基满足三者的受力平衡和变形协调条件。研究了考虑共同作用后的边坡地基强度变形情况及上部框架结构及筏板基础内力和变形情况,得出了对工程实践有参考意义的结论。

关 键 词:共同作用  边坡地基  框架结构  筏板基础  数值分析

Abstract:With the development of cities in mountainous area, some buildings are situated on slope subgrade. Interaction of slope subgrade and the building becomes a realistic research project. By finite element method (FEM), interaction of a frame structure and raft foundation with slope subgrade is computed. The slope subgrade is 10 meters high, slope gradient is 2 : 1, and the building is a ten-story frame structure. In interaction analysis, the interface of superstructure, raft foundation and slope subgrade satisfy the force balance and deformation continuous requirements. Strength and deformation development of the slope subgrade are researched. The internal force and deformation of raft foundation and superstructure are researched simultaneously. Some conclusions useful to the relative engineering practice are obtained.
Keywords:interaction  foundation slope  frame structure  raft foundation  numerical analysis
