昌九城际客运专线作为继京津城际铁路交通建设后的全国第二条城际铁路。
本文主要是针对昌九城际客运专线,结合国家的相关规范对其进行轨道工程设计和施工组织设计以及概预算。本文探讨了在铁路工程施工中对人力、物力和财力的投入,以指导工程施工全过程的技术、经济和组合,便于强化施工管理,保证工程质量。

轨道是铁路固定设备的重要组成部分,其高平顺性是保证开通时达到设计速度的关键。高速、提速铁路只有一次铺设跨区间无缝线路,才能保证轨道具有良好的平顺性。无缝线路以其高速行车、运行平稳和便于养护维修的显著优越性,正逐渐取代普通线路,并成为当今轨道现代化的重要标志。本文针对无缝线路施工的特殊性,根据无缝线路的技术要求,以路基施工为重点,综合介绍无缝线路的铺设技术。本文是在秦沈客运专线的经验上,结合国内外工程实践,总结了一次铺设无缝线路长钢轨的施工技术,对长钢轨焊接、散枕铺设法、长轨排铺设法、换铺法分别进行了简要介绍,进行了一次性铺设跨区间无缝线路的施工程序和施工工艺、设备的研究,为今后的高速铁路跨区间无缝线路的铺设提供了重要的技术储备。
另外,本论文阐述了客运专线工程施工过程中存在常见的问题,分析了成因以及相对应的施工工艺,并总结了施工过程中施工现场管理的作用及应注意的问题,并在秦沈客运专线的经验上,结合国内外工程实践,介绍了主要工程的施工方法,主要劳动力、材料、施工工具数量计算以及铺轨基地的布置,为以后的相关工程提供了重要的技术储备。
总之,本文清楚的介绍了客运专线从设计到施工的主要步骤和方法,也为以后的工程提供了技术支持。

The prosperous nine city border passenger transportation special line takes after the Beijing and Tianjin city border railway communication construction the national second city border railroad. this article is mainly aims at the prosperous nine city border passenger transportation special line, the union country related standard carries on the track engineering design and the construction organization plan to it as well as budgets generally. This article has discussed in the work on the railway construction to the manpower, the physical resource and the financial resource investment, instructs the project to construct the entire process technology, the economy and the combination, is advantageous for the strengthened construction management, the guarantee project quality. the track is the railroad fixed equipment's important component, its Gaoping compliance is guaranteed when clear achieves the design speed the key. High speed, the increased speed railroad only then one time lays down the cross-region welded rails, can guarantee that the track has during the good smoothness. The welded rails by its high speed driving, the movement steady and are advantageous for the maintenance service the remarkable superiority, is substituting for the ordinary line gradually, and becomes now the orbital modernization important symbol. This article in view of the welded rails construction's particularity, according to welded rails' specification, take the roadbed construction as the key point, the synthesis introduced that the welded rails lay down the technology. This article is in Qin at the Shen passenger transportation special line's experience, unifies the domestic and foreign project practice, summarized during one time has laid down the welded rails welded long rail the construction technique, to the welded long rail welding, dispersed the pillow to lay down the law, the long axle platoon to lay down the law, to trade the shop law to carry on separately introduced briefly, carried on disposable has laid down the cross-region welded rails' construction schedule and the construction craft, equipment's research, will lay down for present's high-speed railroad cross-region welded rails has provided the important technological strength. other, the present paper elaborated in the passenger transportation special line project construction process has the common problem, has analyzed the construction craft which the origin as well as corresponds, and summarized the question which in the construction process the job location management's function and should pay attention, and in Qin at the Shen passenger transportation special line's experience, unifies the domestic and foreign project practice, introduced major project's job practice, the main labor force, the material, construction tool quantity calculate as well as lay rails the base arrangement, has provided the important technological strength for the later related project. in brief, this article clear introduction passenger transportation special line from design to construction main step and method, also has provided the technical support for the later project.

Chang The9 occasion of the Beijing-Tianjin passenger line as the following inter-city rail traffic after the construction of the second inter-city rail.
This paper is mainly directed against Chang The9 time when passenger-only lanes, with the relevant norms of their countries to track engineering design and construction design and budget estimate. In this paper, in railway construction in the human, material and financial input to guide the entire process of construction of the technical, economic and composition for strengthening construction management and ensure project quality.

Fixed rail track is an important component of the equipment, its high ride is designed to ensure that opened when the key rate. High-speed, speed rail laying only one cross-CWR can we guarantee that the track has a good ride. CWR its high-speed driving, running a smooth and easy maintenance of significant superiority, are gradually replaced by ordinary lines, and become the track of an important symbol of modernization. In this paper, seamless lines of the special nature, in accordance with the technical requirements of CWR to roadbed construction as the focus, seamlessly integrated circuits on the laying of technology. This paper is in the Qinhuangdao-Shenyang passenger line experience, the combination of domestic and international engineering practice, summed up the laying of a seamless long rail line construction technology, the long rail welding, powder pillow laying of law, laying a long-track row, respectively-for-shop law A brief introduction, the laying of a one-time cross the line between the seamless construction procedures and construction technology, research equipment for future seamless high-speed railway line between the cross-laying provided an important technical reserves.
In addition, the papers on the construction of the passenger line in the course of common problems, analyze the causes and corresponding to the construction technology, and summed up the construction process of the construction site and the role of management should pay attention to the problem, and Qinhuangdao-Shenyang Passenger Green's experience, the combination of domestic and international engineering practice, introduced a method of construction of major projects, mainly labor, materials, construction tools and track laying base for calculating the number of the layout of the related projects for the future provided an important technical reserves.
In short, this article clearly on the passenger line from design to construction of the main steps and methods, but also for the future of the project has provided technical support.
Keyword: Passenger Line; CWR; long rail welding; track laying base construction technology
