摘要

针对现有研究及相关规范中对微地形风场特性考虑不足的问题，文中首先选取了垭口型和高山分水岭型两种典型微地形区域，在考虑地形参数的前提下对其风场分布进行了仿真分析；其次以数学公式的形式建立了风速数据和地形参数之间的关系；最后选取了实际工程中的输电线路为计算案例，进行了风振响应分析，总结了不同微地形对响应数据的影响。文中的研究为经过复杂地形的输电线路设计及运维提供了一些理论依据和研究思路。

Abstract

In view of the insufficient consideration of micro-terrain wind field characteristics in the existing research and relevant specifications

such two typical micro-terrain areas as col type and alpine watershed type are selected firstly in this paper and their wind field distribution is simulated and analyzed on the premise of considering terrain parameters. Then

the relationship between wind velocity data and terrain parameters is set up in the form of mathematical formula. Finally

the transmission line in the actual project is selected as the calculation case to analyze the wind-induced vibration response

and the influence of different micro-terrain on the response data is summarized. The research in this paper provides some theoretical basis and research ideas for the design

operation and maintenance of transmission lines through complex terrain.
