Abstract

The paper outlines the ways to increase the operational reliability of trunk pipelines in the permafrost zone by increasing the soil bearing capacity through the use of technology and technical means to control their physical and chemical properties. The example analyzing the permafrost-soil conditions of the North-East of the European part of Russia proves that the problem of the foundation soil stabilization occurs almost everywhere and requires a solution for a wide range of soils and temperatures. In this regard, the task of improving the operational reliability of trunk pipelines laid in the permafrost zone, using technology and technical means of controlling the physical and chemical properties of soils is a topical subject for studies both from a scientific and practical point of view. The development of new methods for manufacturing composite materials based on cryogels with controlled physical and chemical properties will assist to solve important technical tasks in permafrost conditions. Organizational and technical measures include experimental studies of cryogels for effective soil stabilization, as well as drafting provisions for using cryogels in the construction and operation of facilities in the permafrost zone.
