摘 要随着经济技术的进展和交通运输的进展，铁路的进展也越来越迅速。汉宜铁路是我国“四纵四横”铁路主干网络中沪汉蓉快速客运专线的一部分。铁路以其独特的优点被许多国家作为大力研制和重点进展的目标。本文主要完成汉宜线荆州站接触网平面设计。首先对设计地区的气象条件资料进行了收集，根据铁路目标速度对线索材料进行了选择，再确定其悬挂类型。根据气象条件与线索材料计算负载。其次，根据最大受风偏移计算得到最大跨距；根据规程规定的锚段长度选择锚段，使其力差要满足要求。然后，对硬横跨进行分析选择。最后在上述原理的基础上，重点对汉宜线荆州站接触网进行 CAD 平面设计，并对有代表性的支柱的容量进行了校验计算。本论文以高速接触网的基本技术原理为核心，以实际线路状况为依据，对汉宜线荆州站的接触网布置进行了平面设计，基本满足高速电气化铁路的技术要求。关键词：铁路；接触网；支柱；平面设计重要资料：(2024)1301 接触网 H 型钢柱 (2024)1401-Ⅴ《接触网钢管硬横跨安装构造图》 高速铁路设计规 新建时速 200-250 公里客运专线铁路设计暂行规定（上、下）（施行日期：2005 年 8 月 10 日） 新建时速 200km 客货共线铁路设计暂行规定AbstractRailway is developing more and more rapidly along with the development of economy and transportation, Hanyi railway is part of the Huhanrong personal rapid transit in our four lengthways and crosswise main railway system. Based on its features, Railway has been selected as study and development objectives in many countries.This thesis is mainly focused on the graphic design of overhead line system of Jingzhou station in railway line Hanyi. Firstly, the suspension was selected after the Jingzhou weather condition information was collected and clue material was sift. The load was calculated according to weather condition and clue material. Secondly, the maximum outreach is obtained from the wind shift. Anchoring section is chosen according to specified anchoring section to satisfy tension difference. Then, portal structure was analysed. Finally, on ...
