Публікація Deformation Monitoring of Silos on the Basement, Reinforced with Soil–Cement Elements, Manufactured According to Boring and Mixing Technology(2022) Біда, Сергій Васильович; Bida, S. V.; Marusych, O.; Zotsenko, M.; Pavelieva, A.The construction of a significant number of new facilities takes place on the territories, where geological-engineering conditions are complicated by the pres ence of man-made soils or soils with special properties, which makes it necessary to reinforce the basement. This problem becomes particularly topical in construc tion of such structures as grain storage silos that transfer significant loads to the basement. One of the options for reinforcement is the installation of soil–cement elements, manufactured according to boring and mixing technology. Reinforcement of the basement in this way is quite effective due to the applicability of elements of different diameters and lengths, as well as through adequate choice of distance between them. Variation of these parameters allows to perform reinforcement almost in any geological conditions, taking into account the possibility of consolidation of the bases and foundations below the water table. However, designing and operation of the structures, standing on basements, reinforced in this way, requires intensive study of the stress–strain state of the system “foundation bed–reinforced basement”, taking into account operational features of such structures. Proper allowance must be made for different degrees of silos loading and cyclic loading and unloading. Investigative research of the deformability of such systems is possible by applying various models of soils and the finite-element method as a mathematical apparatus. When choosing a model, consideration must be given to such factors as the accu racy of behavioral model of foundation soils and the simplicity of identification of parameters, required for performing calculations. Special attention should also be given to monitoring the development of subsidence of the structures, built on the reinforced basement, taking into account the time factor for comparison with the results obtained analytically.Публікація Formation of United Territorial Communities Based on the Principle of Urban Agglomerations(2022) Tatarchenko, H.; Biloshytska, N.; Biloshytskyi, M.; Shparber, M.; Біда, Сергій Васильович; Bida, S. V.The paper analyses factors, properties, and criteria contributing to the formation and development of the territorial community based on the principles of urban agglomerations in modern conditions on the example of cities in Luhansk oblast. In the modern world, it is no longer a question of competition between countries but actually between cities–agglomerations or metropolitan cities. In fact, they have been in Ukraine, e.g., large cities of Kyiv, Kharkiv, Lviv. Currently, Ukraine has introduced three levels of the administrative-territorial system, which distinguish the following units: community, district, region. As a part of the decentralization reform in Ukraine, 490 old districts have already been liquidated and 136 new ones have been formed. There have been created 1470 united territorial communities, which should become the basis of local self-government. A criterion analysis of the territory with adjacent settlements has been conducted from the point of view of unification into a territorial community. Priority measures for the development and improvement of the united territorial community as an urban agglomeration have been proposed. Based on the criterion analysis of ‘Severodonetsk-Lysychansk-Rubizhne’ territory with adjacent settlements, we can consider the united territorial community as an urban agglomeration, and develop it as a complex system that includes not only cities and settlements around them, but also all production facilities, resettlement of inhabitants, interaction of nature and urban population as a single entity. For such agglomerations, emphasis should be placed on spatial development, in particular on traditional distribution factors, such as transport, material, labour costs.Публікація Protection of the state geosite – “Pyvykha” mountain under the conditions of the development of sliding processes(2025) Біда, Сергій Васильович; Bida, S. V.; Zotsenko, M. L.; Pavelieva, A. K.; Lapin, M. I.To preserve the state geosite – Pyvykha Mountain, the authors have developed a set of measures to strengthen the landslide slope. However, the work is complicated by the possibility of rockslides and rock collapses, which threatens the equipment and people carrying out strengthening of the shore. After a detailed analysis and generalization of the results of the engineering and geological surveys conducted in this area, the most landslide-hazard zones of the slopes were selected and the stress-strain state of the slope was studied with the help of the Plaxis software complex, considering the possibility of a landslide. According to the simulation results, dangerous zones have been determined within which soil collapses are possible. It was concluded that the presence of people and equipment in these areas should be limited as much as possible.Публікація Research on dynamic impacts on geological environment, soil foundations, and structures(2026-07-13) Mykhailovska, O.; Біда, Сергій Васильович; Bida, S. V.The article analyses the primary methods for determining dynamic characteristics. It has been established that the real environment in which the dynamic processes of seismicexplosive wave propagation occur is not described by an ideal model and is very difficult to describe with equations. The vibration acceleration resulting from the seismic action of explosions in quarry mining and processing plants has been calculated. It has been determined that the calculation can be performed using analytical methods and the finite element method (error of about 4%). It has been established that the application of the finite element method to calculate vibration acceleration during blasting operations in quarries enables the desired value to be calculated at any point of the object under study with reduced working time.
