| 摘 要： | In order to understand clearly to the influence of location and form of HE-charges on the air blast pressure inside the tunnel, based on Hopkinson scaling law, attenuation of air blast peak pressures in long tunnels due to HE-detonations in the case of different location and form at the tunnel entrance is simulated with the dynamic finite element software of LS-DYNA. The results are compared with other experimental methods. The results indicate that the influence of location and form of HE-charges is significant near the HE-charges. As the distance from the HE-charges larger and larger, the influence of location of HE-charges is smaller and smaller, but the influence of form of HE-charges is larger and larger. The methods and data presented can be refereed in similar engineering and determination of loadings upon protective doors.

| Abstract: | In order to understand clearly to the influence of location and form of HE-charges on the air blast pressure inside the tunnel, based on Hopkinson scaling law, attenuation of air blast peak pressures in long tunnels due to HE-detonations in the case of different location and form at the tunnel entrance is simulated with the dynamic finite element software of LS-DYNA. The results are compared with other experimental methods. The results indicate that the influence of location and form of HE-charges is significant near the HE-charges. As the distance from the HE-charges larger and larger, the influence of location of HE-charges is smaller and smaller, but the influence of form of HE-charges is larger and larger. The methods and data presented can be refereed in similar engineering and determination of loadings upon protective doors. |
