Modeling of Blast Effects on Underground Structure

Abstract

Modeling of the impact of a point explosion shock wave on a soil mass and an underground structure at different locations of the explosion epicenter from the ground surface was performed. The study of the stress- strain state of soils was carried out usi ng a nonlinear dynamic method and a fully coupled numerical model, in­cluding various models of materials. The result of numerical modeling showed the adequacy of the adopted nu­merical calculation methods. The findings showed that solving the problem in a nonlinear dynamic formulation allows obtaining the parameters of the shock wave at different depths from the explosion center, as well as ob­taining a complete picture of the interaction of the shock wave with the underground structure in surface and un­derground explosions.

The Bunker - Like a Structure for Storing the Life of the Civilian Population in Conditions of Danger

“…According to one version, the inhabitants of Derink came to the surface only to cultivate the fields, according to another -they lived in the village and hid underground only during raids. In the latter case, they quickly eliminated signs of life on the surface and went underground to hide there for several weeks [13,14].…”
