摘　　要：高压架空输电线路的杆塔类型以角钢塔、钢管杆为主,在一些开阔地带通常选择角钢塔,而在空间受限地区则以钢管杆为主。在埋设钢管杆时,考虑到空间有限、地质复杂,只有对其基础进行优化设计,才能保证基础及钢管杆的牢固。本文结合某工程实例,介绍了工程所在地区的地质条件,进而重点从钢管杆基础类型的选择、基础的优化计算、承台的布置设计等方面,简要分析了钢管杆基础优化设计的具体内容,并从钢管杆的施工及使用角度总结了防撞设计、防腐设计的要点,从而为高压架空输电线路钢管杆的安装及使用提供了技术支持。The pole tower type of high voltage overhead transmission line is mainly Angle steel tower and steel pipe pole. In some open areas, Angle steel towers are usually selected;In the space restricted areas, steel pipe is the main.Considering the limited space and complex geology, the foundation must be optimized to ensure the foundation and the steel pipe to be firm. Based on an engineering example, this paper firstly introduces the geological conditions in the area where the project is located, and then briefly analyzes the specific content of the optimization design of the steel pipe foundation from the aspects of the selection of the steel pipe foundation type, the optimization calculation of the foundation and the layout and design of the cap. Then from the Angle of construction and use of steel pipe, the main points of anti-collision design and anti-corrosion design are summarized, which provides technical support for the installation and use of steel pipe in high voltage overhead transmission lines.
