翻车机室地下结构空间有限元分析与设计

Space finite element analysis and design of wagontipper house underground part

基于STAADPRO有限元软件,利用板单元来模拟地下结构的侧壁和底板,建立翻车机室地下箱型结构的空间有限元模型.通过计算,得到基底反力、侧壁及底板的内力分布,并进行施工图设计.空间有限元分析方法可以充分考虑侧壁、底板、内部框架之间的相互影响,更加接近结构实际受力情况.相对于传统简化算法,其计算结果更合理.

Based on the finite element software STAADPRO,using plate unit to simulate side wall and bottom plate of underground structure,a space finite element model of box structure of a wagon tipper house underground part is established.By analyzing and calculation,the basement reaction,internal force distribution of side wall and base plate are obtained;and the working drawings are designed.The space finite element model can fully consider the mutual influence between wall,floor,and internal framework;therefore,it is more closer to the actual conditions.Compared with the traditional design method,the calculation result with proposed method is more reasonable.
