| 摘 要： | 地基不均匀沉降是导致建筑工程事故的主要原因之一。为了研究地基不均匀沉降对上部结构内力、变形、周期等影响,提出了将地基(或基础)模拟为三维弹性支座的有限元分析方法,将上部结构和地基基础进行整体分析。以深圳市少年宫“水晶石”大厅结构为例,运用有限元软件ANSYS,将三维弹性支承分析法与常用的固定支座法和竖向弹性支承分析法进行了对比分析,验证了三维弹性支承分析法的合理性,从而得出了一些有益的结论,可供设计人员参考。

| Abstract: | Some engineering problems are caused by ground unequal settlements. In order to investigate the influence of the ground unequal settlements on the superstructure, a finite element method simulating ground(or pile ground) is developed by three-dimensional elastic support, which could integrally analyze the interaction among structure, foundation and ground. The comparative analysis among three-dimensianal elastic support,the elastic support model and immobility model for the example of the Crystal Stone Lobby of Juvenile Palace in Shenzhen is done by the ANSYS software of FEM. The method has been proved rationality. Some important conclusions will give advice to structural design. |
