The article is devoted to the study of crowd behavior in public buildings during a fire. A method for evaluating the effectiveness of organizing the evacuation of people from a public building is proposed, which makes it possible to take into account the spread of panic among evacuees. The method is based on the development of an evacuation simulation model that takes into account the impact of certain factors on the degree of people's panic, which implements an agent-based approach. The proposed method allows, when describing the psycho-emotional behavior of each agent separately in the process of evacuation, to evaluate the effectiveness of organizing the evacuation of the crowd as a whole. The simulation results on the example of a shopping and entertainment center show that possible panic conditions of evacuees can affect the efficiency of evacuation.

The article is devoted to the study of problematic issues of the formation of organizational and technical systems of the "cyberpolygons" class using the original methodological apparatus for the feasibility study of system engineering solutions for their construction. The features of existing approaches to the justification of system engineering solutions for the construction of organizational and technical systems, information technology and technical systems are considered. Directions for their development are proposed, taking into account the dynamics of the phased creation and modernization of organizational and technical systems with simultaneously developing infrastructure projects and solutions. Formal aspects in the methodological apparatus are reflected in the change in the composition of the functional components in the conceptual and analytical models, the corresponding formal descriptions of their relationships and characteristics, as well as in the modification of the procedures for the technical and economic assessment of options for building a cyberpolygon. The method of technical and economic evaluation of options for constructing a cyberpolygon proposed in this study makes it possible to rank alternative options for the infrastructures of the created cyberpolygon according to the value of their technical and economic efficiency and to select the rational one from them.

The methods of injection fixing the soils of the base under the foundations of cultural heritage are considered. The specific examples show the features of soil consolidation by cementation and silicatization methods. The technological features of soil consolidation, taking into account the material of the foundations and the technical condition of cultural heritage sites are given

Keywords: cementation, silicatization, injector, soil, consolidation, foundation, object of cultural heritage, sediment, subsidence, deformation

The analysis of the projects for securing the soil foundations, which are part of the new construction projects of educational institutions in the Rostov region in 2016-18, is carried out. On the example of the construction of schools in the cities of Rostov-on-Don, Taganrog, Shakhty, Novocherkassk, Aksai and the village of Chaltyr, the main technical and technological solutions for soil consolidation are considered, depending on the engineering and geological conditions of the construction sites
