Abstract The new Dun-Ge railway passes through sand valley in the east of the Kumtag Desert, the sand source is very rich at the sand valley, the tall dunes are widespread distribution, the hazards of blown sand have caused a serious threat for railway. This study chose DangHe upstream flow sand dunes and Montenegro mouth flow sand dunes as two typical sand dune areas, the system of investigation and observation were carried out concerning the dune water content, vegetation, blown sand environment and hazard. Two sand control demonstration zones were set up in the Danghe River upstream and Montenegro Mouth flow sand dune area respectively on the basis of analyzing the environment characteristic of the two experimental zones. Research was aimed at obtaining the related engineering experience about blown sand protection at sand dune area of railway passing through, confirming reasonable sand prevention and control measures, and providing a theoretical basis and practical reference for the blown sand protection of the railway through the tall dunes area. This research is great significance to ensure railway safety operation.
