架空输电线路设计风速取值分析

风荷载是架空线路设计的关键参数之一,设计风速取值直接关系到线路工程的安全性、经济性以及适用性,设计风速的合理取值有着非常重要的现实意义。本文从设计风速计算密切相关的风压系数取值、地貌类型影响、山区风速以及设计风速新标准几个方面入手,对线路设计风速取值进行了初步探讨。

Taking Value Analysis of Design Wind Velocity for Overhead Power Transmission Line

Wind load is one of the key parameters for the design of overhead power transmission line,it determines the security,economic,suitability of the project,and has practical meaning. The paper has a pilot study of the determination of the design wind velocity from the wind pressure coefficient,landform types,adjustment of mountainous wind velocity and new codes for it.
