    Calculating technogenic vibrations in urban environments using grid-characteristic method
    Computer Research and Modeling, 2025, v. 17, no. 6, pp. 1119-1129

    Amid the ongoing trend of rapid urbanization and the intensive development of megacities and large cities worldwide, the impact of man-made vibrations on residential structures and infrastructure is increasing. The operation of subway systems, construction using pile-driving and drilling equipment, and heavy traffic have become active sources of wave disturbances, which can be a decisive factor in reducing the structural stability of buildings and, consequently, their long-term reliability. This paper proposes a numerical calculation using the grid-characteristic method to model elastic waves propagating through soil layers and load-bearing structures from various sources. By solving the direct problem of numerical pulse simulation and varying its location, the values of velocity vector projections and components of the Cauchy stress tensor were obtained at each time step. Two scenarios were examined: the first simulates the impact of noise generated by construction work or nearby traffic, while the second demonstrates how a subway running through an underground tunnel affects multi-story residential buildings. Wave propagation patterns from these sources were visualized in terms of the parameters of interest, enabling a quick and convenient comprehensive analysis of the problem. The analysis of the obtained data will help adjust the timing and types of repair work, identify structural weak points, and develop innovative methods for preserving historical buildings that are cultural heritage sites. Additionally, it will allow for the most economically optimal construction of modern buildings near architectural landmarks, provide an efficient and safe action plan in emergencies, and modernize existing construction technologies to enhance the comfort of residential buildings, office structures, and other socially significant facilities. It will also aid in selecting the most suitable locations for modern high-precision manufacturing plants.
