毕业设计 甘谷接触网的平面设计.doc

摘 要 作为电气化铁路的重要组成部分，接触网的设计对于整个电气化铁路的设计而言至关重要。设计成果主要以平面布置图和安装图的形式体现，而安装图可选用铁道部通用图，针对各种线路情况，只需进行少量补充，因此，接触网平面设计就成为接触网设计的主要内容。由于各个区间、隧道、车站等线路条件的千变万化，根本无法用固定、简单的格式来完成接触网平面设计，因此必须对每个区间、隧道、车站单独进行平面设计。 本文按照有关的设计标准及规范，重点对甘谷车站进行了接触网平面设计。 在设计中首先按照工程可行性研究报告编制的相关要求，收集与设计项目相关的技术资料，主要考虑兰州铁路局运输生产发展的要求和甘谷车站的长期发展要求，本着经济、合理、可靠、先进的原则，按照具体情况确定设计规模和方案。为了确保安全运营，对气象条件及负载、悬挂导线的张力与弛度、跨距长度、锚段长度以及安装曲线等进行了计算，确保了设计方案的可行性。 在此基础上，绘制了甘谷车站接触网平面设计图，并对设计进行了校核。 关键词: 接触网；车站；平面设计 Abstract As an important part of electrified railway, the design of catenary is critical to the whole design of electrified railway. The production of catenary design is mainly in forms of layout and plan to install. Plans to install can be selected by referring to the optional plans issued by Ministry of Railway, and only a small amount of changes should be added to satisfy different line conditions. Therefore, the graphic design becomes primary part of catenary design. For each interval, tunnel and station have different situations, it is impossible to finish the plan of catenary with fixed, simple format. So, each interval, tunnel and station should be designed alone. In the paper, the graphic design of catenary of Gangu station is mainly conducted in accordance with the relevant design standards and specifications. At first the technical dates which are relative to design project are collected according to the relative requirements which are established by the project feasibility research report, mainly considered the development requirements of Lanzhou Railway Bureau’s transportation production and the long-term development requirements of Gangu station. And in principles of economical, reasonable, reliable and advanced, the design scale and scheme are determined according to the concrete condition. In order to insure the safety luck camp, a series of calculation are carried on about the weather condition and load, the tension and lead of line and the span length, the anchor man segment length and install curve, which e
