Soil influence on partially buried tanks during land explosions

Explosion is considered a sudden load on structure that may result in destructive and unrecoverable consequences. In this article we will study the role of soil in vicinity of concrete tank to lower the influence of explosion. In this study, LS-DYNA (one of the strong modelling programs) has been used for modelling the explosion. The results show that when the mass of explosive matter increases to 3750 KG, the pressure on the soil is about 19.5 times the highest pressure on the tank and which illustrates the role of soil on lowering the influence of pressure.
