Preliminary Experimental Research on Man-made Sand Embankment for Sand Control Along Railway Line

This paper presents chiefly the principle of building up man-made sand embankment for holding back shifting sand from intrusion in the Fusalian Section of the severely cold, dry area along the Qinghai-Tibet Railway Line.It also gives an account of the form and structure of piled-up sand of the sand embankment as well as the results of the sand control measures,through a series of preliminary experimental researches.Building up of the man-made sand control embankment has proved to be an important measure to rid the section of sand disaster.
