Head Haiko Hennadii Ivanovych, Доктор технічних наук Registration Date 02-02-2025 Organization National Technscal University of Ukraine "Kiev Polytechnic Institute". popup.description1 consists in systematic risk assessment and provision of geotechnical protection of the city's underground infrastructure and civil defense structures against critical (explosive) influences popup.description2  The differentiation of underground protective objects was carried out according to the principle of protection against air strikes in cases of direct and indirect (remote from the perimeter of the underground structure) hit by a munition, which strengthens the possibilities of effective introduction into the practice of underground construction of progressive technical solutions and methods of renovation and adaptation of existing underground structures to objects of civil protection. A system toolkit and morphological models were developed for planning the development of urban underground infrastructure with the target function of safety. Their application gives city self-government, state authorities, interested public organizations and investors effective opportunities for making project decisions, based on systemic positions and the social weight of risk factors, in particular - in conditions of military and terrorist threats, which can be considered as an important process of transformation of scientific methods in management actions. An evaluation of the development routes of the underground transport infrastructure was carried out and ratings (priorities) were obtained regarding the expedient sequence of tunnel construction, taking into account the hierarchical weight of the critical infrastructure protection criterion. A mathematical model of the soil massif as a multicomponent visco-plastic medium with a variable viscosity coefficient has been developed, which should be recommended for studies of the stability of underground structures under critical influences using numerical methods. 17 publications were made, of which 8 were published in publications indexed by Scopus and/or Web of Science scientometric databases.
