THE RESULTS OF AN EXPERIMENTAL STUDY OF THE STRENGTH CHARAC-TERISTICS OF BARCHAN SANDS THAT FORM THE RAILWAY SUBGRADE
This paper presents the results of laboratory research of changes in the strength characteristics of barchan sands under the action of vibrodynamic load. Quantitative values of the specific cohesion and the angle of internal friction of barchan sands under static and vibrodynamic loads are given. Dependencies to determine the strength characteristics of barchan sands considering vibrodynamic load in calculations of the railway subgrade strength are proposed.
