With incremented railway construction in wind erosion areas,the problem of wind erosion of railway construction demand more attentions.Experiments are designed against road embankments,soil-excavated fields and sidewalks of Zhangji railway,in order to analyze the relation between the wind speed and sand transport flux,blown-sand structure and sand transport movement.The findings indicate that there is an obvious index relationship between wind speed and sand transport flux in different parts of embankment slope.With variation of blown-sand structure parameters in different parts,erosion of 3-meter design height embankment is independent of wind speed and wind direction and erosion phenomena translate from upwind side to leeward slope side as the wind speed increases and evident relationship between erosion,wind speed and wind direction of not less than 6-meter design height embankment shows up,yet with unobvious wind erosion movement.Wind erosion occurs in diversified segments of sidewalk and soil-excavated fields when wind speed surpasses soil starting wind speed.Studies and conclusions can contribute to the protection layout,construction and environment evaluation both in experimental and theoretical perspective.
