Wind Erosion Controlling Measures Effect of Geerm-Lahsa Section, Qinghai-Tibet Railway
Publication: International Conference on Transportation Engineering 2007
Abstract
The paper studies on the wind erosion control measures efficiency for the roadbed at the worst wind erosion area, Cuona lakeside, Ando county. Its results show that the upright-concrete sand fence has obviously effect on the wind erosion controlling. Especially taking the multiple pieces upright-concrete sand fence system as a comprehensive defense system, it reduced wind velocity by rate 14.41–91.41 % behind the first piece windbreak at difference site as compared to the control, behind second piece windbreak, it reduced wind velocity by rate 37.49∼92.61 %, and 23.44∼87.49 % of the third piece windbreak, respectively. It reduced wind erosion rate range from several times to hundred times as compared to the control according the step-like silt passive sampler calibrated data.
