Construction in northern regions of the Far East is always connected with a high degree of seasonal freezing risk. This is especially true for line transport structures which require a high level of reliability and responsibility. Such structures should provide permissible deformability and bearing capacity of the bases when exposed to moving loads in difficult geological and climatic conditions. The paper considered the development of bridge supports stabilizing structures using mathematical modeling methods and geosynthetic materials. The study used standard methods of engineering calculations using analytical approaches to determine the rational parameters of structural elements and the degree of their operational reliability and durability. In determining the behavior of structures as a whole, with the collaborative interaction of their individual elements with each other, nonlinear soil models of the base of the structures were used. Numerical modeling of bored foundations in an elastic–plastic soil mass allowed to work out effective structural solutions for reducing the deformability of the bridge and increasing the bearing capacity of the pile foundation due to reinforcing measures in the construction of the grillage and creating rational parameters of structures as a whole.

The article considers options for stabilizing the thawing process of permafrost soil of railways during the reconstruction period. The analysis of the engineering and geological conditions made it possible to design rock cooling structures at this facility, which are berms and cover slopes of the subgrade with fractionated rocky soil. The technical characteristics of fractionated rock soil structures have been developed and tested in this cryological area and have shown their effective operation for more than 30 years. As a result of the operation of the railway embankment, permafrost degrades and its boundary is at different depths depending on local conditions and the condition of the drainage systems from the subgrade. The position of the upper permafrost boundary should be established during surveys, if it is not advisable to restore the frozen base to a depth of 10 m, it is necessary to strengthen the thawed weak base and create conditions for the consolidation of thawed soils.

The article provides a way to prevent deformation of linear structures in connection with the laying of the heat mains, which contributes to the formation of ice. The considered pavement design when laying the heating system is being erected on a section of the highway belonging to category III roads. The results of scientific research and engineering calculations of the parameters of rational road structures when laying a heating network are presented using the example of the Far Eastern section of the highway. Development is a generalization of the results of solving engineering, scientific and computational-applied problems. In the considered area, a heating network is laid, which will subsequently warm the outer surface of the asphalt concrete due to the heat generated by the pipes, which will cause ice formation on the outer surface of the asphalt concrete in the period with negative temperatures.

The objective of the work is to develop a rational construction of an artificially prepared base of the foundation, using modern technologies and advanced geosynthetic materials that provide the operational reliability of the structure under special conditions of the construction site. The task of the research study is to develop geotechnical structures, based on the results of numerical modeling of using the properties of modern geosynthetic materials which provides the operational reliability of the joint operation of a weak base with the foundations of a building on Sakhalin Island in accordance with the requirements of regulatory documents operating in the Russian Federation.
