Comparison of Protective Measures Against Wind Blown Sand on Railway

In the flat area of Northwest China, subgrade engineering, as a more economical and efficient structural form, plays leading role in railway engineering. Therefore, wind sand prevention engineering needs to be studied. To prevent control damage scientifically, we must correctly understand types principles measures. At present, main measures protect from are vegetation measures, such planting grass cultivating forests; high vertical barrier, stone (grass) grid or density polyethylene Anti-sand net; chemical fixation spraying agents for fixation. order compare which kind protection project is suitable use environment Shashangou landform, according mechanical principle design review opinions former Ministry railways, have designed new test section at small mileage side Bridge on Dunhuang Golmud railway, adopted variety section. this paper, based case observation hazard effects various compared. same time, bridge (replacing road with bridge) also included comparison measure, forms qualitatively compared popularized. The fixed most reasonable; typical desert environment, form suitable. whole life cycle, economy better than that
