摘要
采用三维可调节点弹塑性有限元-无限元-壳体有限元耦合计算模型,分析了广州新中国大厦建筑基础与既有下部人防洞室共同作用的空间效应,并将基础荷载作用下地下洞室的位移状态与现场量测结果进行了对比验证,由此得出了片筏基础至地下洞室的最小安全距离和一些有关结论。这些研究成果除了能对工程的顺利实施起着十分重要的指导作用外,还可为以后类似工程积累经验和实践资料。
By using 3D node-adjustable elasticoplastic finite-infinite-shell element coupling calculation model, the spatial action between the building foundation of Guangzhou New-China mansion and the existed underground shelter cave is analyzed in this paper. The calculated displacement of underground cave under foundation load is compared with measurement results in site and is approved reliable. The safe distance between building foundation and underground cave and some other concerned conclusions are obtained. The study results not only serve as important inference to the construction of this case, but also accumulate experience and data for other similar engineering practices.
