本文所论工程1000kV淮南-上海(皖电东送)输电线路,是我国第1条百万等级的双回路特高压线路,电压等级高、导线截面大、平均塔高超过110m,采用钢管塔结构技术经济优势明显.加工产能是制约钢管塔应用最主要的原因,本工程设计中,在广泛调研和充分吸收国内外先进设计理念的前提下,提出了钢管塔标准化设计,应用带颈锻造法兰、标准化插板管头并规范和统一了可供设计选用的钢管系列规格库,为皖电东送工程钢管塔设计的安全可靠、制造加工的规范高效创造了条件.本文同时论述了工程进行的1基科研试验塔、8基工程真型塔和1基Q460科研试验塔的真型实验,以及相关的钢管、法兰、插板、节点、高强度螺栓等一系列试验研究.试验结果进一步指导和完善了钢管塔的设计,在计算模型、主材径厚比、结构布置、加劲板设置和构造处理等方面对钢管塔设计有了新的理解和认识.%Huainan-shanghai 1000kV UHVAC transmission line studied in this paper is the first project of double circuits UHV transmission line in China. The characteristic is UHV? large section of conductor and average highness more than 110m. It is more reasonable and economical for using steel tubular tower. Manufactory producible capability, that is primary reason restriet to using steel tubular tower. In the design of this project, standard design of steel tubular tower was put for ward after studing advanced method at home and abroad. One series of steel tubes, 3 kinds of joint plates of member-end and forging flange with neck were used, which create the conditions for design safty and efficient production of steel tubular tower. Testing research was carried on for 10 steel tubular tower (1 for study ? 8 for engineering and 1 for Q460 study ) to study properties of steel tubular? flange? joint plate? main joint and high strength bolt. So that design theories of steel tubular tower was improved. It is necessary and important to be different from angle tower such as beam-truss models of analysis? reasonable length-to-diameter ratios? approprate idth-to-thickness ratios? logical structure layout? plate of supporting main beam and otherwise method. This article support good idea for desigh of steel tubular tower.`
