摘　　要：在试验的基础上,运用ANSYS/LS-DYNA有限元分析软件对触爆作用下单层厚板的抗爆性能进行数值模拟计算,对爆炸波在钢筋混凝土板中传播及震塌破坏做了全过程三维数值模拟,通过数值模拟可以更加清楚地认识单层厚板在触爆条件下的破坏机理,模拟计算的破坏现象和试验结果取得了良好的一致性。Combining experiment of reinforced concrete slab under contact explosion and using ANSYS/LS-DYNA finite element analysis software,a 3D numerical simulation was conducted for single layer slab in the situation of contact explore.The whole process of detonation,blast propagation and vibration damage are displayed.The mechanism of vibration damage of single layer slab under contact explore is understood more distinctly by numerical simulation,the damage phenomena of simulation agree well with experimental macroscopic result.
