铁路客运专线优秀毕业的设计.docVIP

摘要 本设计主要是针对新建铁路客运专线无砟轨道测量问题及线路中桩坐标计算程序的编辑做了研究。 通过对国外国内客运专线的发展简况、客运专线无碴轨道结构特点、较为广泛使用的几种无砟轨道结构形式、客运专线特点、客运专线控制测量方法与特点等的简单介绍；通过对CPIII控制网的起算基准、网形设计、精度设计、精度指标和客运专线无砟轨道施工要求要求等的全面介绍，进行了铁路中线坐标计算程序编辑工作，并对无砟轨道的拨道量计算进行了试验性的编程。 在本设计第二章主要是对高速铁路的轨道测量坐标系统的选择以及CPⅢ基桩控制网和轨道的精调进行了阐述；第三章对铁路中线坐标计算的意义以及计算过程怎样通过程序语言的实现进行了阐述，并且对无砟轨道拨道量的计算程序的编程原理进行了介绍。在附录中给出了中桩坐标程序的部分源程序。 关键词： 客运专线 无砟轨道 CPIII 中线坐标 Abstract This design is mainly directed against the ballastless track measurement problem of the new high-speed passenger transportation special line and the edition in the program of center pile coordinate calculation of the lines. Based on a simple introduction of the development of the passenger transportation special line in domestic and foreign, the ballastless track structural characteristics of passenger transportation special line, the ballastless track structural forms widely used, the characteristics of passenger transportation special line, and a comprehensive introduction of benchmark data of CPIII control network, net form design, accuracy design, accuracy demand and The ballastless track construction requirements of the passenger transportation special line, I have completed the editing work for the program of center pile coordinate calculation of the lines, and finished the experimental programming of the amount of ballastless track movement. In the second chapter is designed for the track surveying coordinate system selection of high-speed railway and precision adjustments of CPIII control net and the tracks. The third chapter interprets the significance of railway centre line coordinate calculation and the program implementing of calculating process, and introduces the programming’s calculation principles of the amount of ballastless track movement. It provides a part of program code of center pile coordinate calculation in appendix.
