Based on the study of wind controlling measures efficiency at the K1533 of Qinghai-Tibet railway

the results show that the upright sand fence decreased the wind velocity in the protection area

behind the first piece upright sand fence

it reduced wind velocity by rate 14.63%~86.15% as compared to the control

41.93%~97.91 % behind second piece

and 22.80%~87.40 % behind third piece

respectively.The wind erosion modulus decreased greatly behind the upright sand fence

after the first piece of upright sand fence

the wind erosion modulus just occupying about 21.75% of the control wind erosion modulus.Wind erosion rate behind second and third piece upright sand fence

it reduced range from several ten fold to hundred fold as compared to the control.The same trends appears in the stone checkerboard sand barrier protection area

wind erosion modulus reduced range from several ten fold to hundred fold

even to thousand fold as compared to the control in the same monitoring height.Upright sand fence and stone checkerboard sand-barrier have the greatly effect on the wind erosion control of the railway

their protected that the railway suffered from the wind erosion hazards.
