Abstract: The airport is a complex and especially responsible engineering structure. The construction of which can take place in any, very often difficult engineering and geological conditions. The tasks of a geological engineer include not only engineering and geological surveys and writing summary reports, but also recommendations on artificial management of soil properties so that they can be used in human engineering and economic activities. Quite often, when detecting soils unfavorable for construction, designers suggest cutting them off and replacing them with others, which is not always economically justified. However, it is possible to achieve stabilization of the soil base in less expensive ways: using methods of technical soil reclamation and engineering protection of territories. This article provides an engineering and geological justification for the use of technical land reclamation methods to stabilize the soil base during the reconstruction of an airport located in the Arctic zone in the absence of frozen soils in the base (using the example of Murmansk airport). Methodology of development of complexes of engineering protection of the airport territory Murmansk includes an analysis of regulatory documents, an analysis of the results of engineering and geological surveys, an analysis of methods of technical soil reclamation recommended in connection with the data of engineering and geological surveys, a design methodology, and positive experience in using solutions at similar facilities. Scientific novelty of the work:1) a methodology has been developed for the engineering and geological justification of the complex of engineering protection of the territory to stabilize the soil base of the airport territory. Murmansk for the construction and reconstruction of linear structures based on the analysis of regulatory documents, design decisions, engineering and geological information and the method of analogies; 3) a complex of engineering protection of the Murmansk airport territory aimed at stabilizing the groundwater base is substantiated.Conclusions: When stabilizing the soil base under the runway, taxiway, aprons, etc. of Murmansk airport, it is necessary to apply a complex of engineering protection of the territory, including mechanical, physico-chemical methods, as well as methods for stabilizing the soil base with geosynthetic materials. Based on the engineering and geological conditions of the territory and the features of airport construction (alkaline environment), the use of geocomposites from PVS raw materials will be optimal, which is also confirmed by the economic benefits.
