摘要
新疆大风不仅能吹倒送电线路的铁塔,还能倾覆旅客列车。据我院新疆大风调研收集到的资料统计,托克逊最长大风持续日数20天;阿拉山口、达坂城和哈巴河的最长大风持续时间超过40h;阿拉山口多年平均大风日数最多,达163.8天;阿拉山口气象站实测最大风速为46.0m/s;阿拉山口据基本风压推算离地10m高100年一遇设计风速约为50m/s;新疆自治区已建送电线路采用的最大设计风速为44m/s。新疆大风持续时间之长、风速之大、范围之广是其境内的工程建设必须予以重视的。建议尽可能充分利用工程地段附近测风塔的风速资料作大风灾害评价。
Xinjiang winds blew down not only the tower of power transmission line, but also capsized passenger train.According to my research hospital Xinjiang wind statistics collected, Tuokexun maximum sustained winds for several days 20 days; Alashankou, dabancheng Habahe winds and the longest duration more than 40 h; Alashankou years up to the average number of windy days, reaching 163.8 days; Alashankou Station measured maximum wind speed of 46.0 m/s; Alashankou basic wind pressure according to projections from the ground 10 m high in 100 years the design wind speed of about 50 m/s; the Xinjiang Autonomous Region has been built to send a maximum design wind speed electrical lines used to 44 m/s.Long duration of strong winds in Xinjiang, wind speeds, the broad scope of its domestic construction projects must be valued. Recommends that full use of wind data engineering area near the masts for wind hazard assessment as possible.
