基于Midas的基坑换撑有限元分析

Supportive replacement of deep excavation based on Midas

换撑是基坑施工中的重要技术。通过对上海某地铁基坑换撑时的有限元分析,计算了各换撑工况支护结构的受力及位移情况,确立了施工过程中的最危险工况。

Supportive replacement is an important technique in deep excavation.The load conditions and displacements are analyzed based on FEM method.The most dangerous working condition is also defined.
