Numerical Analysis of Underground Tunnels Induced by Ground Truck Explosion

The present study attempts to analyze the dynamic response of underground box tunnel at depth 4m using nonlinear finite element software Ansys/LS-Dyna. Arbitrary Lagrangian-Eularian (ALE) numerical solver had been used to evaluate tunnel responses when it subjected to two kinds of trucks explosion (small delivery and container/water truck) filled with maximum TNT charge weight 1814 and 4536 kg, respectively. The results indicate that the container truck explosion caused great increment in displacement, velocity, and effective stress values as compared with small delivery truck. The top wall corner and roof center of the tunnel had faced maximum deformation and velocity in both cases of trucks explosion. In addition the value of effective stresses was high in roof edge and top wall corner.
