MAIN GEOTECHNICAL PROBLEMS OF RAILWAYS AND ROADS IN KRIOLITOZONE AND THEIR SOLUTIONS

摘要

In Transbaikal and in the adjacent territories including China for the last 20 years was activated the building of railroad and highways. Experience of development anti-deformation measures for the Russian and Chinese railroads and highways with utilization active methods of strengthening of the railway embankment on ice-rich permafrost is illuminated. New technical solutions anti-frost heaving devices for contact-line and airline supports on permafrost and a deep seasonal freezing of the soils, providing decrease of forces of a regulation seasonally-thawed soils with a lateral area of a support and reduction of their power and humidity are defined also at simultaneous magnifying of pinching down action of the transmission tower footing by upheaval of a roofing of permafrost by means of the taken out a patent for modes;;experience of design and the installation new anti-frost heaving devices is featured at renovation of an overhead contact system Transbaikal railroad.
