摘要
结合输电线路铁塔结构的特点,对国内外高强钢的应用现状、使用高强钢的技术经济性、高强角钢市场供货能力、高强钢设计技术参数的选取等方面进行了探讨和研究。输电线路铁塔中使用高强钢,既有明显的技术经济效益,又有利于提高我国输电线路的建设水平。
The paper discussed and studied the application situation of high strength steel overseas and domestic, technique and economy of high strength steel, supply capacity of materials of high strength angle steel in market and choice of high strength steel design technical parameters by combining with the structure characteristic of transmis- sion line tower. Using high strength steel in power transmission tower not only has an obvious technical and economical benefit, but also can promote the construction level of power transmission line in China.
