The purpose of the article is to publish the procedure for determining the resistance of underground structures to the shock-explosive action of adjusted aircraft bombs.The course of the Russian-Ukrainian war shows that currently one of the most dangerous means of defeating our troops in defensive positions are adjusted aerial bombs. Under such conditions, an effective way to protect personnel and material and technical means from enemy strikes is to shelter them in underground structures that must be resistant to the shock-explosive action of these weapons.The article presents the procedure for determining the resistance of underground structures to the shock-explosive action of adjusted aviation bombs, in particular FAB-500 M62 with a universal planning and adjustment module, using calculations of the required value of the protective of the soil layer of underground structures, which consists of determining the depth of penetration of a corrected aircraft bomb into the soil and calculating the radius of the sphere of destruction of the soil layer of the structure.The scientific novelty of the proposed calculations lies in the comprehensive consideration of indicators, the numerical values of which characterize: the final velocity of the aircraft bomb at the moment of impact; the depth of its penetration, taking into account the inclined position in the protective soil layer of an underground structure; radius of the sphere of destruction of the protective soil the thickness of this structure, taking into account the bomb penetration coefficient; tactical and technical characteristics of the FAB-500 M62.The practical significance of the results obtained lies in the obtained formalized description of the sequence of calculations for determining the resistance of underground structures to the shock-explosive action of adjusted aviation bombs and the ability of commanders (chiefs),military command bodies to more correctly determine the stability of the specified structures and promptly make appropriate decisions regarding effective shelter and protection of personnel and material and technical means from enemy strikes.
