摘要
应用熵最大原理导出的概率模式研究了新疆建筑工程设计中最大风速的分布规律 ,并通过近100个气象观测站36年(1961～1996年)资料的分析 ,发现新疆最大风速若干规律性 ,在此基础上 ,建立了新疆风压系数预测模式为 :W。=0.0613e -0.0001h ,以预测模式和概率模式揭示了新疆风压分布特征。结果表明 :新疆大多数气象观测站的最大风速遵循Г分布 ;新疆风压系数随海拔高度的增加呈指数率减少 ;新疆风压分布特征为 :北疆大于南疆 ,西部、东部大于中部 ;高山和高原地区大于中低山区。风口、河谷风压值最大。塔里木油田地区风压特征为 :由东北向西南递减。这对于新疆建筑工程设计及相关的电力、公路等工程设计都具有重要的科学意义和使用价值。
Maximum wind speed distribution law in building design in Xinjiang is studied by the entropy maximum principle. Some regularities of maximum wind in Xinjiang is studied by analyzing 36a observational data from about 100 meteorological stations .And then,a predicting model on wind pressure coefficient in Xinjiang is built,that is W0 =0.0613e-0.0001h .Distributive feature of wind pressure in Xinjiang is disclosed by prediction model and probability model. The results show that maximum wind speeds at most meteorological stations obey Γ-distribution and wind pressure coefficients decreased exponentially with height above sea level.Distributive features of wind pressure in Xinjiang are:wind pressures in north Xinjiang are bigger than those in south Xinjiang, wind pressures in west and east Xinjiang are bigger than those in middle Xinjiang; wind pressures in plateau and high mountain are bigger than those below middle mountain. Wind pressures in wind and valley of river are maximum. Distributive features of wind pressure in oil field of Talimu are that wind pressures are decline from northeast to southwest.These results are important to building design and other electricity and highway designs.
