新疆克塔铁路沿线导风板作用下风雪流场的仿真分析
Simulation and Analysis of Wind and Snow Flow Field under the Action of Wind Deflector along Karamay-Tacheng Railway in Xinjiang
冬季时风吹雪灾害给位于中国新疆西北地区的克塔铁路(克拉玛依—塔城)的安全运营带来极大的障碍,为了防治该灾害,采用数值模拟方法,研究了克塔铁路沿线50年重现期风速下导风板不同高度和角度设计参数对既定铁路路堤周围风雪流场的影响以及路堤周围的积雪分布情况。结果表明:在50年重现期风速下,增大导风板与主风向的布设角度,会减弱导风板对风雪流的输导作用。导风板角度设置为60°时,呈现出最佳的导雪效果。增加导风板的布设高度,会增大其加速区覆盖范围,此时更有利于风雪流顺利通过,从而降低雪颗粒的堆积概率。导风板高度设置为2 m时,具有较高的性价比。
In order to prevent and control the snow drifting disaster along the Karamay-Tacheng Railway in northwest of Xinjiang, numerical simulation method was adopted to study the influence of different height and angle parameters of wind deflector on the snow flow field around a given railway embankment in 50-year recurrence period in this paper. The results show that increasing the angle between the wind deflector and the prevailing wind direction will weaken its effect on snow dispersion in the 50-year recurrence period. When the angle is set to 60°, the snow dispersion effect is the best. Increasing the height of the wind deflector will increase the coverage of the acceleration zone, which is more conducive to disperse snow flow and reduce the probability of snow particle accumulation. When the height is set to 2 m, it's a cost-effective solution.
