4.2 A NEW GROUND FLOOR DIAGNOSTIC DEVICE

Abstract

In this article, the concept of a diagnostic system using geophysical methods for specific railway track conditions, the elements of the diagnostic system are: the object of research; methods and technical means of diagnosis; classification of diagnostic signs (criteria for identifying deformations); trained technical personnel interacting with the object of research according to the rules established by the relevant regulatory and methodological documentation; expert opinion on the technical condition of the roadbed with an indication of the location, type and cause of deformations.

Keywords: Diagnostics, roadbed, soil properties, georadar, diagnostics of the main site, deformation, deep ground reference points, inclinometers, strain gauges, stresses.

Introduction. The roadbed diagnostics system is based on the use of both traditional and new geophysical methods, modern measuring equipment and computer technologies. The diagnostic system also uses specially designed mobile diagnostic laboratories. The basis of the diagnostic system of the roadbed is made up of geophysical methods, which are based on the study of anomalies of physical fields caused by changes in the lithological structure of the roadbed, the difference in physical and mechanical.
