The study of railway embankment deformations in cold regions

Abstract

Concerning the need for railway capacity increase, the trains marshaled of innovative cars with 27 t axle load are being tested at the test sites. At one of the sites of Sverdlovsk Railway, 100 km Kachkanar—Smychka, the works have been organized to provide geodetic monitoring of the permanent way and the high embankment formation deformations. The geodetic surveys were carried out for eight months from December 2017 to July 2018 at four test sites. The analysis of the measurements shows an intensive frost heaving of the soils at two test sites in winter period. The permanent deformations of the main site of the formation were observed at these sites in summer period.
