Quantitative characteristics of surface runoff from railway tracks

Abstract

Analysis is carried out and the nature of surface runoff filtration in the ballast prism of the railway track is considered, as well as options for water migration in the upper and lower structure of the ballast prism are considered. The formula of flow rate of rain, melt and filtration runoff is obtained. The formula for surface runoff consumption from the railway track was clarified, and the total surface runoff flow rates for the areas of railway transport facilities were determined. It was found that when surface water seeps through the upper and lower structures of the path. Two lateral ejections occur. The proposed methodology for determining the flow rates of surface runoff from railway tracks allows using an adapted methodology proposed not for residential zones, which is relevant for 90% of the railway bed located in the Russian Federation, in particular, the Kuibyshev railway road located in the forest-steppe and semi-steppe zones.
