在建筑物外部一定距离上设置防爆墙,能对汽车炸弹爆炸冲击波和碎片起到有效的防护,消除爆炸冲击波对建筑物及内部人员的破坏杀伤作用。主要应用Ansys LS-DYNA程序,建立了爆炸荷载作用下悬臂式防爆墙有限元模型,分析了防爆墙的破坏机理,以及防爆墙极限状态下的承载力和变形情况,所用方法和成果可供防爆墙设计时应用参考。 Explosion-proof walls located at a distance from the outside of the building can effectively protect the car bomb blast wave and debris and eliminate the damaging effect of the blast shock wave on buildings and internal personnel. The finite element model of cantilever explosion-proof wall under explosive load is established by Ansys LS-DYNA program. The failure mechanism of explosion-proof wall and the bearing capacity and deformation under the limit state of explosion-proof wall are analyzed. The methods and results are available for explosion proof Wall design application reference.
