中文摘要: 使用陕西北部16个气象台站的风速资料,利用幂函数、逐步回归、皮尔森Ⅲ型、曲线模拟等统计方法,进行了陕西省330kV榆林至神木高压输电线路沿途距地面15m高度15年一遇的10min平均最大风速的极值推断。其模式为y=-575.6277+222.4759lgx-0.0678x。最后提出设计最大风速建议值为30ms-1
Abstract:Based on wind data of 16 meteorological stations in north part of Shaanxi province, by using power function, successive regression, K.Pearson Ⅲ type and curve fitting, the extreme value of maximum wind speed was estimated for 300kv high pressure transmission line from Yulin to Shenmu, which happened every 15 years at 15m above the ground. And the design value of maximum wind speed was finally suggested to be 30m·s-1.
