摘要

为节约用地，山地城镇建设中有些建筑建于岩坡地基上，岩坡地基与上部建筑结构之间的共同作用分析成为山区岩土工程实践中的一个课题。基于有限元分析的数值方法，对均质岩坡上建筑边距(建筑距坡顶边缘的距离)对上部建筑结构与地基基础相互作用的影响进行了计算分析，其中边坡地基为10 m高的直立岩坡，基础为平板式筏基，建筑边距分别考虑了2、5、8 m的3种情况。研究了3种建筑边距情况下边坡地基的强度变形情况及上部框架结构、筏板基础的内力和变形情况，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。得出了相关结论，对工程实践有一定参考意义

Abstract

With the development of cities in mountainous area

some buildings have to be situated on rock slope subgrade in order to save land. Interaction of slope subgrade and the building become a realistic research project. By using finite element method

interaction of a frame structure and raft foundation with homogeneous rock slope subgrade is computed. The computation examples are considered in 2m

5m and 8m building distance circumstances. Rock slope subgrade is a 10 meters high vertical slope and foundation is raft. In interaction analysis

the interface of superstructure

raft foundation and slope subgrade satisfied the force balance and deformation compatibility requirements. In three building distances circumstances

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 are drawn

so as to offer for reference in related engineering practice
