摘要:
数值模型尺寸参照总参工程兵科研三所所建的穿廊结构坑道实体模型，采用ANSYS/LS-DYNA建立三维穿廊端部不同开闭的数值模型，得出冲击波在多级穿廊结构坑道内的传播规律，并与长直坑道内爆炸冲击波传播规律进行对比分析。结果表明多级穿廊结构端部开放坑道对爆炸冲击波的削弱作用非常显著，一级穿廊结构削弱冲击波强度62%，级数越高，削弱效果越明显；端部封堵时冲击波反射效果明显。
Abstract:
The size of numerical model referred to a physical model built by Luoyang Institution of Hydraulic Engineering and Technology. To study the propagation on mechanism of explosion shockwave in its entrance to a multilevel gallery tunnel,the software ANSYS/LSDYNA was used to calculate the change process of explosion field and it was compared with the straight tunnel when the ends of the gallery tunnel are open or close .The results showed that most energy of blast shock wave can be reduced when the ends of the gallery are open,onelevel gallery reduces the energy of blast shock wave to 62 percent compared with the straight tunnel.The effect on the reflection of blast shock wave from the ends of the tunnel is significant when the ends of the gallery tunnel are close.
