摘要
研究了支护结构对上部框架结构—筏基—地基的共同作用体系的作用,建立了共同作用体系有限元模型.利用有限元分析程序SuperSAP,对考虑与不考虑支护结构、不同土质和不同支护桩长度和刚度作了对比计算.结果表明:考虑支护结构后基础沉降计算值减少,但同时基础的内力计算值增大;支护结构可以分担建筑物的部分荷载,影响地基承载力.通过对支护结构的作用效果分析,对实际工程设计提出了一些有益的结论.
The effect of the supporting pile on the interaction system of structure, raft foundation and soil is studied. The finite element model of the interaction system is set up. Based on the finite element analysis program——Super SAP, the comparative study of considering or not considering supporting pile, the different condition of soil, the different depth of foundation and the different length and rigidity of the supporting pile are conducted. The computing results indicate that with the supporting pile the raft settlement decreases, but the foundation's interior force increases, and the supporting pile can share the building force and affect the soil bearing force. Through the effecting analyses of the supporting pile, some helpful results are made for the practice design .
