Study on optimization of sand blocking measures and their protection effect along desert highway
摘要
Abstract
As the first barrier for desert highway protection,the sand barrier fence is very important to the safety of the route.The CFD numerical simulation is used to compare and analyze the effect of windproof and sand prevention before and after the improvement of the sand barrier fence.The results show that the near-sur-face horizontal wind speed and average wind-proof efficiency between the first and second fences have little change in the improvement scheme of sand blocking fence with the height of 2.5 m and the spacing of 20 m,compared with that in the initial scheme of sand-blocking fence with 2.0 m in height and 25 m in spacing.The near-surface horizontal wind speed decrease by 13.63％and 17.63％,and the average wind-proof efficiency increase by 10.26％and 18.46％between the second and third sand-blocking fences and between the third sand-blocking fence and the high-vertical large-grid sand barrier,respectively.The thickness of sand accumu-lation in the rear area of the three sand-blocking fences increase by 15.79％,50％and 40％respectively.When the improved scheme is adopted,the sand deposition range completely covers the entire sand accumula-tion area,and the sedimentation on the top of the embankment is significantly reduced,which means the im-provement scheme has a better windproof and sand prevention effect.关键词
