Electrical Resistivity Tomography and Electrocontact Dynamic Probing along the Railroad for Geotechnical Forecast

The paper presents the results of investigation of railroad bed foundation on a section of bridge crossing. Geological structure of the area was studied for identifying the preconditions of landsliding processes. Geophysical methods were used to investigate the distribution of electrical resistivity in the section and to determine the mechanical properties of soils. The results of processing and joint interpretation of geological and geophysical data allowed constructing a geological and geophysical model and drawing up the geotechnical forecast.
