FIELD MEASUREMENTS OF TYPHOON CHARACTERISTICS NEAR GROUND IN WENZHOU COASTAL FLAT TERRAIN

  • 摘要: 为研究温州滨海平坦地貌近地台风特性,在温州滨海建立了风工程实测基地(塔高10 m),并利用台风"菲特"和"麦德姆"登陆过程中不同高度处风速及风向实测数据,研究了10 m高度范围内的平均风速和风向角、湍流度、阵风因子、湍流积分尺度和功率谱密度等风特性参数。结果表明:离地10 m高度范围内,实测风速剖面系数明显大于该地貌的规范取值,风速平均值和最大值均明显小于国家规范计算值;不同高度处横风向与顺风向湍流度比值随着高度减小而增大,实测湍流度与我国规范取值差异较大;顺风向,湍流积分尺度与平均风速之间的线性规律较好,随着高度增加湍流积分尺度离散性变大,湍流积分尺度的中位数与平均值差别不大,均小于日本规范;顺风向和横风向脉动风速功率谱有一定的变化,峰值频率和峰值都很接近,实测脉动风速的功率谱与Von Karman谱在数值上有一定的差异,但变化趋势基本一致。
