| Abstract: | Metro is a significant component of the lifeline engineering,and it has the characteristics of huge cost,long service cycle and densely populated personnels during the operation,which makes it a target of the terrorism bomb attack easily.In order to avoid severe destructions and even progressive collapse of the metro station under the terrorism bomb attack,numerical calculation model of the metro station was built by three-dimensional analysis software LS-DYNA3D,and the inner exlopsion effect was analyzed a... |
