基于空间计算的地铁明挖车站受力规律分析

Analysis for stress rule of open-cut metro station on spatial computation model

以某地铁明挖车站为例,采用ANSYS空间整体模型,计算分析了在不同覆土厚度、不同基础持力边界条件下,车站主要结构构件的内力变化规律,得出了一些有价值的结论,为地铁车站施工提供了依据。

Taking the open-excavation subway station as an example,applying ANSYS spatial integral model,the paper analyzes internal force changing law of major subway station structure components under conditions of different soil-covering stratum thickness and different fundamental bearing boundary,and obtains some valuable conclusions,which has provided some basis for subway station construction.
