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