论文题目：无砟轨道的养护与维修 中文摘要 无砟轨道是以混凝土或沥青混合料等取代散粒道砟道床而组成的轨道结构形式，高速铁路的发展史证明：无砟轨道是具有平顺性高、刚度均匀性好，轨道几何形位能持久保持、维修工作量显著减少等特点，在各国得到迅速发展。特别是高速铁路，一些国家已把无砟轨道作为轨道的主要结构形式进行全面推广，并取得显著的经济效益和社会效益。 从高速铁路设计、施工来论证铁路工程测量的精度要求。叙述无砟轨道施工测量控制网的施测和复测要求以及无砟轨道施工测量原理、线路精确测量，并提出无砟轨道施工测量的质量控制措施，可为高速铁路其他形式的无砟轨道施工测量提供参考。 无砟轨道是当今世界上先进的轨道技术，与有砟轨道相比，它具有相当高的技术经济性，同时可以减少维护，降低粉尘，美化环境，列车时速可达二百公里以上。关键字： 无砟轨道； 施工测量； 控制网 ；测量精度； 技术经济性 Abstract Non-ballasted track is concrete or asphalt etc. instead of shot ballast track bed whichconsists of the track structure high-speed railway history that: non-ballasted track is ahigh smoothness stiffness good uniformity track geometry potential energy tomaintain a lasting significant reduction in maintenance workload characteristics invarious countries have developed rapidly. Especially high-speed railway a number ofcountries have non-ballasted track as a track form the main structure of the generalpromotion of and achieved remarkable economic and social benefits.From high-speed railway design construction to prove the accuracy of themeasurement requirements of railway engineering.Describes the non-ballasted trackconstruction survey control network of test facilities and retest requirements andnon-ballasted track construction measuring principle accurate measurement of the lineand made non-ballasted track construction survey of quality control measures for otherforms of high-speed railway construction of non-ballasted track measurementreference.Non-Track is the worlds advanced rail technology compared with ballasted track ithas a very high technical and economic.
