摘要

摘要: 针对海岛地形下强风爬坡效应对输电塔和跨海大桥的不利影响，基于计算流体力学软件，以浙江沿海一座具有塔架工程建设背景的岛屿为研究对象，采用数值仿真的手段研究了不同坡度海岛的竖向风速分布规律，并对坡顶区域竖向风速进行拟合。研究发现：最大竖向风速出现在迎风坡约3/5高度处；距海岛顶部150 m高度范围内，坡顶竖向风速随坡度的分布近似满足指数型函数，当超过该高度时，竖向风速随坡度基本不变；不同坡度工况下，坡顶以上最大竖向风速出现在距坡顶50~200 m高度范围内。

Abstract: Considering the adverse effects of strong wind climbing on transmission towers and sea-crossing bridges under island terrain, an island with the tower engineering construction background along the Zhejiang coast was studied based on Computational Fluid Dynamics. The vertical wind speed distribution of islands with different slopes was studied by numerical simulation, and the vertical wind speed at the top of the slope was fitted. The results showed that the maximum vertical wind speed was at about 3/5 height of the windward slope. Within the height range of 150 m from the measured point to the top of the island, the distribution of the vertical wind speed on the top of the slope with the gradient approximated to an exponential function, and when it exceeded this range, the vertical wind speed remainsed unchanged with the gradient. Under different slope conditions, the maximum vertical wind speed above the top of the slope was in the range of 50~200 m from the top of the slope.
