ELASTIC VERTICAL DEFORMATION OF COMPACT-SOIL RAILWAY EMBANKMENTS

VERTIKAL'NY UPRUGIE DEFORMACU ZELEZNODOROZNYH NASYPEJ IZ SVJAZNYH GRUNTOR

The article presents the results of experimental studies on the distribution of elastic deformations in embankments; determines the pattern of possible deformations of embankment slopes; shows the influence of loads per axle and per unit of length, on the variation in the values of the elastic deformations. With the same static load per axle, there occurs, for 8-axle wagons elastic vertical deformations 30% greater than those produced in the case of 4-axle wagons; this phenomenon must be borne in mind when designing the structures of 8-axle bogie wagons, and in track-bed and track-structure consolidation work on busy lines. A linear relationship has been identified between the axleloads of a wagon with running-gear of current design, and the elastic deformations of the track bed. By extrapolating the data obtained to those used during the tests, possible values can be envisaged for elastic vertical deformations of the track bed.
