Analysis of calculation methods for explosion shock wave parameters in the design of protective structures

Relevance. The full-scale invasion of the Russian into Ukraine revealed a fairly large number of issues, including those related to the construction of defensive and fortification structures. As it turned out, this direction in our country has not actually developed. There is no regulatory framework for taking into account many specific factors, such as the blast shock wave, penetration by ammunition and fragments (fragments). It should be noted separately that the means of attack are constantly developing and improving, and this requires constant improvement in countering them. This article is devoted to a review of existing methods that can be used to determine the parameters of the blast shock wave, which should be used when calculating building structures and structures. Choosing the right method for the calculation will allow you to work out a methodical approach to the design of fortifications, structures for engineering protection of critical infrastructure, and civil defense structures, and this is a very important and relevant task. This approach can later be included in specialized regulatory documents for the calculation and design of defensive and fortification structures, which would significantly improve their quality and reliability, taking into account modern wartime threats. The aim of the work is to review existing methods of engineering and analytical calculations of parameters of explosive shock waves and building structures and structures for damage by enemy attack means. The importance of choosing the correct calculation method for different types of threats is a very important task for the correct design of fortification and protective structures. Results. The paper considers existing global methods for determining the parameters of explosive shock waves for calculating building structures and structures for damage by enemy attack means. The issue of the need to develop a clear engineering method for calculating building structures and structures for the action of an explosive shock wave is raised. Algorithms for determining the parameters of explosive shock waves and further calculating building structures of fortifications and engineering protective structures for damage by enemy attack means are presented.
