| 摘 要： | 运用大型有限元软件LS-DYNA，在相同爆炸冲击波作用下，对坑道口部普通钢板防护门前面不设置泡沫铝缓冲层和设置泡沫铝缓冲层两种情况分别进行了数值模拟和对比分析，结果表明：泡沫铝缓冲层对爆炸冲击波峰值压力有着良好的衰减特性，对坑道口部抗爆炸冲击波设计有着一定的参考价值。

| Abstract: | Using the finite element software LS-DYNA, under the same blast wave loading, numerical simulation is respectively clone for the response of general steel defensive structure and steel defensive structure with aluminum foam buffer before general steel. Comparative analysis is made with numerical simulation＇ s result of the two defensive structure. The result shows that steel defensive structure with aluminum foam buffer behind general steel has a good attenuation characteristic for peak pressure of blast wave. It is proved that the new defensive structure is worth applying in anti-blast design of the entrance of tunnel. |
