为提高新疆风区公路,特别是高速公路的行车稳定性和安全性,研究基于不同防风构造物的现场观测结果,对其防风效果进行了比较,推荐了防风效果较优的结构形式。在此基础之上,对防风效果优良并在实际工程中使用最为广泛的开口板式防风栅进行了深入的分析;利用计算流体模拟软件对防风栅的设置和风速的影响进行了分析,对3种典型车辆(小轿车、大客车和大货车)在不同组合条件下的风场中受力状态和稳定性进行分析和比较,提出了挡风墙的最佳设置方案,并推荐了临界设计风速,对风害防控设计提出了参考意见。
In order to improve driving stability and safety of highway in Xinjiang, especially on expressway, the comparison of the wind-proof effect based on the observation results of different wind-proof structures was made and the structure with better wind-proof effect was recommended. On the basis of this, the windbreak effect is excellent and the most widely used open plank weatherproof grille in practical engineering is analyzed in depth; the use of computational fluid simulation software to analyze the setting of windbreak and wind speed is analyzed. Typical vehicles (cars, buses and large trucks) under different combinations of wind conditions and stability of the wind farm to analyze and compare the proposed wind wall optimal setting programs, and recommended the critical design wind speed, The paper puts forward some suggestions for the prevention and control of wind damage.
