“…A number of scientific papers are devoted to the issues of influence of various types of impacts (dynamic, seismic, vibration) on the condition of underground pipelines [3][4][5][6]. It is necessary to point out that dynamic, seismic, vibration effects on the condition of underground pipelines are similar in their destructive ability and, consequently, scientific papers devoted to this topic can be used to analyze the existing problem.…”

“…The article [5] presents the results of a study of the effect of rail fasteners on the vibrodynamic effect of rolling stock transmitted to the ground of the roadway and then to underground pipelines. Changes in the amplitude values of the soils were recorded with an increase in the speed of passing trains.…”

The present paper presents the rolling stock vibrodynamic impact model on railway pipelines, obtained on the basis of experimental studies conducted under field conditions at a railway station. The experimental research program provided for the determination of the effect of vibration-dynamic effects of rolling stock on the working condition of pipes and butt joints by conducting vibration-measuring work on the investigated section of the railway pipeline during the passage of various series of locomotives. The proposed modeling method makes it possible to obtain a correlation function of the oscillatory process of a railway pipeline, on the basis of which a spectral density is constructed to identify the amplitude-frequency range at which a stable resonance region occurs, leading to the destruction of the pipeline.

The research results are presented – chemical properties (evaluation of the detoxifying ability of silica sol), physical (determination of the required concentration of silicon dioxide), and physico-mechanical (strength tests of samples) – the properties of silicas. Transport construction technologies are proposed in which the use of a new binder allows achieving higher strength indicators of fortified structures, as well as ensuring the fulfillment of the geoecological function and recycling of roads by using silica sol.
