Numerical Simulation of Blast Shock Waves Propagation Effected by Cross Section Shape of Tunnel

摘要：

Using LS-DYNA software, ALE algorithm and the multi-material fluid-structure coupling manner, blast shock waves propagation in the tunnel of square section，rotundity section and vaulting section are studied by numerical simulation. The results show that the differences between shock wave pressures at the corresponding characteristic points of explosive axis tunnel of square section，rotundity section and vaulting section; The identity of reflective pressure cures of several characteristic points on the inner surface of the tunnel. These results have important value for controlling of explosive in the tunnel.
