| Title of the article | Influence of the foundation and soil structure on reducing the level of vibrations arising from the movement of metro trains |
| Abstract. | Problem statement. The metro tunnels construction in conditions of cramped urban development is a technogenic risk source for existing and newly designed buildings and structures. In turn, the construction of new buildings may negatively affect the operating conditions of metro structures. In this regard, when designing buildings and structures in the area of metro lines, it is necessary to carry out a comprehensive assessment of their mutual influence. The purpose of the work is a geotechnical forecast of the influence of the metro on the designed building in Kazan and the influence of the building on the metro. The objectives of the study are the selection of the most optimal design of the foundation and soil base, which allows reducing the level of vibrations on the surface of the foundation from the influence of the movement of metro trains to the permissible limit, and calculation of the base of the foundation of the designed building based on deformations, taking into account the vibration impact from the movement of metro trains. Results. The design solution for the base and foundation of the designed building, selected by calculations, providing for the installation of a slab foundation on a compacted layer of crushed stone with a thickness of 1000 mm, makes it possible to reduce the level of vibrations from the movement of metro trains to the permissible limits provided for by sanitary standards SN 2.2.4-2.1.8.566-96. Conclusions. The significance of the results obtained for the construction industry is that the approaches to calculations recommended in this article and the results obtained for a specific structure can be used in the development of measures that reduce the negative mutual influence of newly designed buildings and the metro. |
