摘　　要：接触网是大变形的柔性索结构。高速铁路的整体吊弦施工要求在安装施工前就确定吊弦的长度。本文利用有限单元法,建立针对完整锚段找形的计算模型,并对平曲线、缓和曲线等各种线路情况提出了修正方法。文中对郑西客运专线多种线路情况的实际锚段吊弦长度进行计算。对比计算结果表明,在多种线路情况下的计算精度与SIEMENS公司的Candrop软件相当。The overhead contact system is a flexible cable structure with large deflection. To meet the construc- tion requirements of the complete set of droppers in the high-speed railway, the accurate dropper lengths will be calculated before the droppers are assembled. Using the finite element method, this paper has established a form-finding calculation model for the dropper lengths in an entirely insulated section, in which two kinds of line conditions have been considered： horizontal curves and transition curves. The dropper lengths of several sections of the Zhengzhou-Xi ~ an Dedicated Passenger Railway Line have been computed. Compared with the computed results of SIEMENS＇s Candrop,precision of the provided model is equivalent to Candrop^s under the above line conditions.
