国内外输电线路杆塔设计标准对比分析

Comparison Analysis Between Domestic and Foreign Standard in Design of Transmission Line Tower

随着国家"一带一路"战略政策的出台,国内电力企业纷纷走向国际市场,境外电网项目越来越多,了解和掌握国内外杆塔设计标准的差异是目前境外输电线路项目中亟待解决的问题,对控制工程的造价、质量尤为重要。本文结合实际工程,分别从杆塔安全度、荷载及构件计算等方面进行了分析对比,并通过实例计算及铁塔真型力学试验验证,分析结果可为境外输电线路工程设计提供参考。

With the introduction of the national strategic policy of ＂The Belt and Road Initiative＂, domestic electric power enterprises are moving into the international market extensively. Along with the increasing offshore power grid projects, to understand and knowledge the differences between domestic and foreign standards in design of the towers is becoming an urgent problem to be solved at present in power transmission line projects. It＇s very important to control the cost and quality of engineering. With combination of practical engineering, tower safety degree, loads and member calculation are compared and analyzed respectively in this thesis, which are also verified by calculation examples and tower type mechanical test. The analysis results can provide references for the overseas project design of transmission line.
