| Abstract: | This paper analyzes the characteristics of climate, geology and geomorphology, vegetation, and sand dune distribution in
the Cuonahu Lake area beside the Qinghai-Tibet Railway. The types and causes of railway blown-sand hazards are discussed,
and the effectiveness of various sand-controlling measures is assessed. From the perspective of integrated management,
a sand-controlling system that combines several engineering measures, including nylon net sand barriers, concrete
sand barriers, movable-board sand barriers, sand interception ditches, gravel/rock cover, film sandbags, and permanent
vegetation is most beneficial. |
