STATION'S PLANE DESIGN OF CATENARY BASED ON CAD TECHNOLOGY （THE FUXIA INTERCITY A STATION）
摘要
现代高速铁路绝大多数都是采用电力牵引方式。接触网设计特别是高速接触网设计过程包含了大量的设计计算、绘图、校验等工作。单靠人工设计工程量大，且质量难以保证。为了减少接触网设计人员的工作负担，缩短设计周期，提高设计质量，保证电气化铁路运行的安全性和可靠性，使用计算机辅助设计是非常必要的。本设计是基于CAD制图系统进行站场接触网的平面设计，完成了福厦城际A站的250km/h高速铁路接触网平面布置图的设计和绘制。本次设计就是采用AutoCAD2007为制图工具，依据相应的计算结果、站场气象条件和地质条件等对正线和站线进行相关的跨距的选择，支柱布置和类型选取以及锚段长度的划分，再按照设计手册中的相关要求在表格栏中对侧面限界、支柱类型、地质情况、安装图号等进行相应的表述。
高速接触网与普速接触网无论在设计还是施工方面，都有着许多的不同之处。因此，在本设计中运用了普速接触网所没有的技术。同时，本设计还注重各方面的因素考虑，以使本设计在技术、经济、美观方面都达到基本的要求。另外，在设计后期，本文对接触网的特点进行了分析，对高速接触网与普速接触网的主要差异进行了探讨，对高速铁路接触网部分施工关键技术进行了阐释，为设计和施工提供必要的参考与指导。

Abstract
Most modern high-speed railway is adopted electrical traction. Catenary design but especially in high-speed catenary design process contains a large amount of job like design calculation, drawing, checking,and so on. The project amounts are big if it depends solely on a manpower designing, and it is difficult to guarantee the quality. In order to reduce the contact network designers work, shorten the design cycle, improve design quality, and ensure the safety and reliability of electrified railway's operation, the use of computer-aided design is very necessary. The design which is based on the CAD drawing system has finished Station's Plane Design of catenary, completed the Fuxia A station 250km/h high-speed railway catenary floor plan design and drawing. This design is the use of AutoCAD2007 as mapping tools, according to the corresponding results, station weather conditions and geological conditions on the line and station lines are related to the choice of the span, pillar layout and type selection and the anchor length of the division, Then in accordance with the relevant requirements of the design manual column in the table on the side of the gauge, pillar type, geology, such as installation of the corresponding figure number expressed.
High-speed catenary and the normal-speed catenary design or construction, have a lot of difference. Therefore, the technology which this design used does not make use of by the normal-speed catenary design.At the same time, pay attention to all aspects of design considerations to enable the design of technical, economic, and aesthetic aspects of basic requirements to meet. In addition, late in the design, the paper touches the characteristics of catenary, discussed the mayor differences between the high-speed catenary and the normal-speed catenary, explained the key technology of the high-speed railway catenary construction to provide necessary reference and guidance.
