架空送电线路铁塔基础扭转偏差的讨论

Discussion on the Torsion Bias of Pylon Foundation in Overhead Power Line Construction

关于架空送电线路施工中基础扭转偏差的问题,本文通过研究相关条文规定,提出了铁塔基础在回填夯实后,两轴线与设计要求的两个轴线之间的偏差角即是基础扭转偏差。而转角塔基础的两个轴线则需由设计通过电气间隙、铁塔导线布置及基础的荷载情况来确定。

On the torsion bias of foundation in overhead power line construction, this paper through the study of relevant provisions, provides that pylon foundation after the backfill tamped, deviation angle between the actual and the design two axis is the basis of the torsion bias. And the two axis of angle tower foundation is required by the electric clearance, conductor and tower layout and foundation from design to determine.
