ENSURING RESISTANCE OF UNDERGROUND CRITICAL INFRASTRUCTURE OBJECTS OF SHORT DEPTH TO MISSILE ATTACKS

Abstract

Protection of the population and critical infrastructure from missile attacks is one of the current challenges for countries involved in military conflicts. The geopolitical situation exacerbates the risk of expanding existing conflicts to new countries. The example of Ukraine shows that missile attacks not only pose threats to the civilian population, but also cause destabilization of the energy system, disruption of the operating modes of engineering facilities for gas supply, water supply and sewage, which creates significant risks for the stable and safe functioning of cities.The high threat of energy collapse has been repeatedly confirmed during the period of war in Ukraine. One of the most effective methods of protecting critical infrastructure from air attacks is their transfer underground. This study proposes the use of finite element numerical simulation to determine the parameters of deepening and protection of engineering communications and structures. A numerical model was developed and the impact of the explosive load on the soil mass was assessed using the ANSYS Explicit Dynamics software. The patterns of soil behavior under explosive load were obtained, including the dynamics of crater formation and destruction zones, which creates the basis for obtaining the parameters of deepening of engineering systems in various soils. The authors believe that the results obtained will contribute to sustainable development and global security and will be useful to countries in which there is a risk of military conflicts.
