摘　　要：对特高压交流小根开铁塔ZBC2910Z进行建模计算及优化设计,寻找其合理的塔身坡度,分析了其优化布置后的受力及变形特征。采用ANSYS软件建立了酒杯型小根开铁塔ZBC2910Z的三维数值模型,研究了其典型呼高的动力响应特征。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特高压工程中应用可行性。In this paper, the modeling calculation and optimized design are made for some Small-Base-Tangent- Towers （ZBC2910Z） to obtain the reasonable and optimized slope of the tower body for the UHV transmission project. The deformation properties and behavior mechanism of the appointed tower of the optimal H/B （ratio of tower height to tower base width）, are analyzed according to the results of the IGT software. The three dimensional FEA models of ZBC2910Z are built, whose dynamic characteristics are simulated and obtained with the ANSYS software. Finally, based on an analysis of the technical and economic factors, it is found that the Small- Base-Tower has good terrain adaptability and therefore it is of important significance in the UHV transmission project.
