Abstract. Currently, with the development of many cities, the need for transport infrastructure is increasing. Since the free ground space in urban environments is limited, the most effective and efficient exit is the construction of underground structures. Currently, new underground construction projects are being developed in conditions of high density of development, and in many cases in areas where ancient structures and buildings of historical value are located.

The effectiveness of design solutions for the protection of objects in the zone of tunneling depends on the accuracy and reliability of methods that assess the impact of factors that have a negative impact. Moreover, if the station complexes are often built in areas with minimal impact on the surrounding buildings, and their construction is carried out by means of small mechanization and small visits, then the construction of tunnels, in the zone of their influence can get buildings of historical and cultural value. The authors of the article have considered both the causes of sediment and empirical, analytical and numerical methods for their evaluation. In particular, among the analytical methods, the method developed in MIIT and based on the reciprocity theorem was distinguished. The article also compares the calculation results for precipitation method Yu.A. Limanowa and calculation in program complex PLAXIS. In the end, the authors give conclusions based on the analysis of all the above methods, as well as recommendations for reducing sediment during tunneling with the use of tunnel mechanized complexes.
