The Dynamic Response of Shallow Buried Structure under the Action of Explosion Load

Abstract:

Simulating and analyzing the dynamic response of the shallow underground structure under the ground explosions by LS-DYNA. The results show that the ground shock under ground explosions contains two different forms, one is direct impact ground shock and the other is indirect impact ground shock; with the increasing of depth, the ground shock decreases. The effective stress of the upper part of the roof is larger than other parts of the shallow underground structure; the effective strain of the corner of the roof is larger than other parts of the shallow underground structure.
