摘　　要：研究目的:对无砟轨道的误差源和误差传递规律进行分析,提出降低误差的相应措施,最大限度的降低误差传递和无砟轨道施工误差,提高无砟轨道初始精度,保证轨道综合质量。研究结论:通过对无砟轨道误差源进行的定性、定量分析,其合成误差中各分项的权值是动态变化的,经研究提出了其权值分配;施工中应选择合理的施工方案、重视扣件系统管理、保证轨道测量的可靠;以工程技术控制为主线,将工序、标准落实到每个工作岗位,采用先进的设备避免误差传递和积累,最终保证无砟轨道工程质量。Research purposes：This paper analyzes the error resource and error transferring regulation of ballatless track and offers the measures for reducing the error for the purposes of reducing the error transfer and the construction error of ballastless track,improving the accuracy of initial ballastless track and ensuring the comprehensive quality of track.Research conclusions：From the qualitative and quantitative analyses it is known the weight values of all sub-items are variable,and the distribution of the weight values are offered through the study.In the course of construction,the rational construction scheme should be chosen,the attention should be paid to the fastening management,and the measurement reliability of track should be ensured,the construction technology should be taken as the control sector,the construction procedure and standard should be implemented to every job,and the advanced construction machinery should be used to avoid the the error transfer and accumulation and guarantee the the construction quality of ballastless track.
