新疆风区铁路长达525km,占线路总长的27.6％,主要风口有安西风口、百里风区、三十里风口、达板城风口和阿拉山口。上述地区每年大风天数超过100天,其中阿拉山口最长高达156天。大风风速40m/s,瞬间最大风速达到64m/s。 兰新铁路自通车30多年来,大风曾给铁路安全运输造成严重威胁和重大经济损失。据统计,吹翻列车13起,吹翻车辆79辆,经济损失4200多万元。此外,大风使路基造成严重风蚀变形,对蓬布车造成很大破坏,甚至发生人员伤亡。 挡风墙是防止大风吹翻列车有效的工程措施。
Xinjiang’s windy railway up to 525km, accounting for 27.6% of the total length of the line, the main outlet with Anxi outlet, Baili wind area, thirty miles outlet, up to the city outlet and Alashankou. The annual windy days more than 100 days, of which the Alashankou up to 156 days. Gale wind speed 40m / s, instantaneous maximum wind speed of 64m / s. For more than 30 years since the Lan-Xin Railway opened to traffic, strong winds have posed a serious threat to railroad safe transport and major economic losses. According to statistics, blowing 13 trains, blowing 80 vehicles, economic losses of more than 4200 million. In addition, strong winds caused severe wind erosion and deformation of the embankment, causing great damage to Pengbu vehicles and even causing casualties. Wind wall is to prevent the wind blowing over the train effective engineering measures.
