中文摘要[目的]研究沙漠地区交通线路周围侧向输导工程的风沙流场规律,为侧向输导工程的应用提供理论基础。[方法]基于新疆维吾尔自治区哈密市了墩地区风信数据和CFD三维数值模拟,建立不同工况对3种侧向输导工程的风沙流场进行对比分析。[结果] 3种侧向输导工程由于结构的不同,风沙流通过开放式羽毛排的排间间距进行侧向输导,封闭式羽毛排和一字排则在排前进行输导。3种侧向输导工程流场作用区域都由输导区和减速区构成,但开放式羽毛排的减速区面积明显小于封闭式羽毛排和一字排。风速较大沙源丰富应使用一字排,风速较大沙源一般应使用开放式羽毛排,风速一般沙源丰富应使用封闭式羽毛排。[结论]侧向输导工程可以对风沙流进行有效输导,不同类型的侧向输导结构适用于不同的工况。
英文摘要[Objective] Studying the rules of wind and sand flow in lateral transport engineering around desert line to provide theoretical basis for the application of lateral transmission engineering. [Methods] Based on the wind data in the Liaodun area of Xinjiang Autonomous Region and 3D numerical simulation of CFD, the wind and sand flow fields of three lateral transmission engineerings were compared and analyzed under different working conditions. [Results] Due to the structure differences of lateral transportation engineering, wind and sand flow were guided laterally by the spacing of open feather-row, while closed feather-row and straight-row were conducted in front of the engineering. The flow field of three lateral transportation engineerings were all consist of the transportation area and the deceleration zone, but the deceleration zone area of open feather-row was less than those of the other two. Large wind speed and rich sand source should use straight-row engineering. Large wind speed and general sand source should use open feather-row engineering; general wind speed and rich sand source should use closed feather-row engineering. [Conclusion] Lateral transport engineering can effectively transport wind sand flow, and different types of lateral transportation structure are suitable for different conditions.
