摘要
为了解决输电线路铁塔结构设计中遇到的导线横担斜材布置问题,以某直流接地极直线塔的设计情况为例,采用东北电力设计院编制的自立式铁塔内力分析软件(2.0版),对导线横担上平面、下平面和正平面斜材布置方式进行受力计算分析,建议:横担平面应尽量采用斜材不受力的方式,下平面根部斜材应与塔身横隔材的中点相连,正平面斜材的受力计算应考虑实际施工需要。
In order to handle layout of diagonal member of crossarm for transmission lines on steel tower, the paper adopts software for stress analysis on self-reliance tower （edition 2. 0） compiled by Northeast Electric Power Design Institute to calculate on stress of layout of diagonal member at upper plane, down plane and front plane. It is suggested that there should be no stress on diagonal member, diagonal member at root part of down plane should connect with middle point of horizontal member and stress calculation on front member should take construction into consideration.
