Application of radar sounding of subsurface studies in the assessment of freight car descents

Abstract

The article discusses the causes of rolling stock derailments. At present, train derailments are investigated for external deviations of parts and assemblies, without considering the internal side of the development of emergency situations. The deviations that depend on the structure of the roadbed and are controlled by the center for diagnostics and monitoring of infrastructure devices should be noted. But the reasons are not always revealed which lie in the condition of the roadbed and the belonging of the site to the mountainous terrain or the direct section where the groundwater passes. It is the structure of the roadbed and the moisture content of the layers that affect the formation of subsidence of the track, which may result in dangerous situations when moving rolling stock. To monitor such areas, a certain system is needed that tracks the state of the path not by external signs, but by layers of the roadbed. That is what a geo-radiolocation system is that allows to “shine through” rocks with the help of radio waves and to determine in detail the deviations and changes in the structure of the roadbed, as well as to identify increased moisture content of layers for timely prevention of soil erosion and subsidence under the embankment. This research technique is not only economical, but also quite convenient when examining large areas of the railway track.
