摘　　要：特高压输电工程中采用小根开铁塔,可以满足立塔受限区段(地形陡峭、场地狭窄等)的工程需要。针对特高压小根开直线塔ZBC2910Z进行优化设计,寻找其合理的塔身坡度,分析其优化布置后的受力及变形特征。采用ANSYS软件建立酒杯型铁塔ZBC2910Z的三维数值模型,研究其典型呼高的动力响应特征。最后,通过技术和经济分析论述了小根开铁塔具有良好的地形适应性和应用可行性。In UHV transmission line project,Small-Base-Tower was applied in espceially complicated mountain areas,to meet the needs of steep terrain tower location.The paper firstly carried out optimized design for some Small-Base-Tangent-Tower ZBC2910Z to seek out its reasonable and optimizing slope of the tower body.Moreover,the deformation properties and behavior mechanism of the appointed Tower,which held the optimal H/B （ratio of tower height to tower base width）,was analyzed according to the results of IGT software.Specially,the three dimensional FEA models of ZBC2910Z were built,whose dynamic characteristics were simulated and obtained in this paper with the ANSYS software.Finally,considering technical and economic factors,the application of Small-Base-Tower with good terrain adaptability has a very important significance in UHV transmission project.
