Abstract
The present study aims at establishing a fully coupled 3D numerical approach for analyzing
the response of buried structure subjected to subsurface blast loading. In this approach, the
explosion source, the propagation of stress wave in the soil and the interaction between soil
and the structure are integrated into a single model. The validity of proposal model was
established by comparison of the obtained numerical results with the available field test. The
model is then used to study the effect of medium on buried structure response. Increasing the
structural resistance efficiency to withstand ground shock from subsurface explosion was
achieved by introducing ground shock attenuation sand layer in the front of wall facing the
explosion source. The finite element hydrocode ‘AUTODYN’ was employed.
