| 摘 要： | 运用大型有限元软件LS—DYNA，在相同爆炸冲击波作用下，对坑道中不设置泡沫铝缓冲层和设置泡沫铝缓冲层2种情况进行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有着良好的衰减特性，这对坑道口部抗爆炸冲击波设计有着很高的参考价值，为新型抗冲击缓冲材料提供了设计基础。

| Abstract: | Using the finite element software LS-DYNA,under the same blast wave loading,numerical simulation is done for the(response) of common concrete defensive structure and concrete defensive structure with buffer of aluminum foam.Comparative analysis is made with numerical simulation's result of the two defensive structure.The result shows that buffer of aluminum foam has a good shock attenuation characteristic.It is proved that aluminum foam is worth applying in anti-blast design of tunnel exit.The results obtained could be used as a design basis when aluminum foam is chosen as new anti-impact buffer material. |
