摘要: 兰新高铁是世界上穿越最长风区、防风工程规模最大的铁路。大风严重威胁高铁的运营安全,查明兰新高铁沿线大风分布特征及危害特性极为重要和迫切。利用气候分析、天气诊断及实测校验等方法,结合兰新高铁沿线大风观测资料,找出了微地貌、特定气候导致的局部特大风速区段,确定了沿线大风风速、风向在平面、剖面方向的时空变化规律。基于地形、风力、大风频率及危害程度,将兰新高铁线路划分为五大风区的防风工程设计分区,即:大风极少区、大风低发区、大风一般区、大风易发区和大风频繁区。大风区线路应以降高度、小夹角、大半径为主要选线原则。防风工程的设计,应以大风工程分区为基础,评估不同工程风区环境下的列车安全特性,建立以大风工程分区匹配为主导,适合不同风区,结合设置条件的系统工程对策。
关键词: 兰新高铁大风规律工程分区防风对策    
Abstract: Lanzhou-Urumqi high-speed railway crosses the longest strong wind area and is also the largest scale of windproof engineering railway in the world. Strong wind threatens the safety of high-speed operations. It is very important and urgent to clarify the distributions, characteristics and hazard features of strong wind along Lanzhou-Urumqi high-speed railway. This paper analyzed the strong wind monitoring data along the railway by climate analysis, weather diagnosis and actual measured check, etc. It was found that the local extra-strong wind zones influenced by microtopography and specific climate conditions. The spatial-temporal variations of wind speed and wind direction in both areal and vertical along the railway were also pointed out. Moreover, this research divided five strong wind areas into different design subareas of windproof engineering by the approach of Windproof Engineering Subarea, which is based on terrain, wind power, frequency of strong wind and hazardous amplitude. In addition, the design subareas are very-low-frequency strong wind area, low-frequency strong wind area, general-frequency strong wind area, high-frequency strong wind area and very high-frequency strong wind area. The principle of route selection in strong wind area should comply with a principle of decreasing height, shortening angle and enlarging radius. On the basis of engineering subareas it evaluates safety characteristics of trains in different engineering subareas when designing of windproof engineering, it establishes systematically engineering countermeasures which is led by matching the design subarea of windproof engineering, it also combined with engineering conditions and fit for different engineering subareas.
Key words: Lanzhou-Urumqi high-speed railway    law of strong wind    windproof    subarea of engineering
