Abstract

The paper covers the results of phenomena and process researches that influence deformations in soil bases in the annual cycle. The target research focuses on deformations in an embankment under operation in severe natural climatic, engineering and geological conditions. The causes of a road exploitation in permafrost areas with cryogenic deformations are presented. It is necessary to reduce the length of sections under the slow order that has been introduced due to unpredictable deformations in the embankment, while the sections are located in complex natural, climatic, geological and engineering conditions. In addition, it is necessary to provide a planned strengthening of the embankment, thus preventing appearance of deformations, and carry out a reconstruction of the embankment on the sections expecting an increasing volume of coal. A cause-effect analysis of processes and phenomena in soils fosters justification of designs and their better selection for improving mechanical strength characteristics that accord with natural restoring processes in soils (drainage and strengthening). A rational justification of the roadbed strengthening and a testing introduction are mandatory requirements for the roadbed design that provides the technical system bearing capacity with developed and patented technical solutions.
