Abstract

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.
