PROBLEMS RELATED TO TRACK AND TRACK MAINTENANCE

VAPROSY PUTI I PUTEVOGO KHOZIAISTVA

This issue presents the following reports: (1) Loads, speeds, load stress, track operational experience of rolling stock abroad, tentative communications - long life of rails, long contact life of rails, long life of rail according to individual operational output, wood-tie outputs, cleansing and replenishment of the ballast layer, current track repair, composite indices. (2) Estimate of the dynamic influences of rolling stock during the calculation of the stability of railroad embankments; methodical indications for the calculation of dynamic effects of rolling stock at the time of computation of the stability of the subgrade slopes (embankments), experimental and theoretical calculation bases of "methodical indications", modeling the embankments in the presence of the dynamic effect of train loads, calculations of the reliability of the embankments, analysis and synthesis of the results of modeling and calculations. (3) Experimental analysis of several design solutions on swamp subgrades. (4) The study of the work of electrical controllers during the investigation of destruction of maximum condition of embankment models. (5) Spheres for rational application of various road packers on the construction of railroads.
