摘　　要：为得到带端撑750 k V变电构架不同根开下的最优方案,采用SAP 2000软件对进出线根开尺寸为6,7,8 m的钢管混凝土人字柱变电构架进行有限元分析,并对纯钢管变电构架和各根开情况下的钢管混凝土变电构架结构的截面尺寸进行初步设计,分析其经济性。结果表明:在满足承载力要求的前提下,根开尺寸为8 m的方案为最优方案,具有一定的经济效益。To get oplimal scheme of different root size of 750 kV subslation framework with braced columns at the ends, 6 m-root size, 7 m-root size and 8 m-root size concrete filled steel tube herringbone column substation framework had been analyzed by SAP 2000, the section of the steel tubular structures and different root size of concrete filled steel tubular herringbone substalion framework had been preliminarily designed, whose economy was analyzed. The resuhs showed that the 8 m-root size herringbone column framework was the optimal design, and it had economic benefit.
