架空输电线路荷载规范中导线风荷载的分析OA
Analysis and Comparison of Load Specification for Overhead Transmission Lines
《架空输电线路荷载规范》正逐步代替旧规范.成为重要的设计依据,主导今后架空输电线路工程中杆塔荷载的设计工作.本文主要研究《架空输电线路荷载规范》中线条风荷载的计算,通过对脉动风以及阵风系数、档距折减系数与风振系数等新系数的研究,解析系数背后的物理意义,并将其与旧规范计算结果进行比较.
The Code for Overhead Transmission Line Load is gradually replacing the current code.It has become an important design basis,leading the design work of tower load in overhead transmission line engineering in the future.This paper mainly studies on The Code for Overhead Transmission Line Load in the line of wind load calculation,through to the fluctuating wind and wind coefficient,gear reduction factor,and coefficient of wind vibration coefficient and other new research,the physical meaning behind the analytic coefficient and its calculation results compared with the current specification.
