Determination of loads of blast wave on aboveground and underground structures

The article covers the problem of determination loads blast wave on aboveground and underground structures. In industrial production, chemical sources explosion occur, for which environment is air. most common typical source solid products (PE) in form a packed charge. explosion, highly compressed heated gaseous are formed volume main parameters shock that determine its effect structure, i.e., excess pressure front, time wave's actionτ, impulse have been determined according to empirical formulas obtained by experiment each source. Therefore, this work, determining incident large-scale experimental studies presented. It has found structure barriers buildings increase significantly as result secondary returning waves superimposing first wave.
