Abstract
EN: Abstract. The results of the study of the ballast layer consolidation after the work of ballast-tamping
machines of different types are given in the article. The existing methods of determining the degree
of consolidation of the ballast layer are analysed. The seismic method was improved by means of a
complex dynamic and kinematic interpretation of the impulse response. For the dynamic interpretation
with the use of statistical analysis, the features are selected so that they correspond to the degree of
consolidation of the ballast layer. On the basis of researches, a device and software were developed
that allow an automated evaluation of the ballast layer consolidation based on the kinematic and
dynamic analysis of the measured impulse response. The measurements of the degree of the ballast
layer consolidation after an operation of ballast-consolidation machines in different sequences allowed
establishing the efficiency of the consolidation and the feasibility of the machines’ application.
