摘要
针对目前既有线有砟轨道大养测量效率和测量可靠性较低的缺陷,通过与传统有砟轨道大机养道整道测量方法对比,提出了-一种基于移动RTK快速连续测量新方法,并通过现场实测试验及轨道线形模拟,验证了新的方法可以满足现有大机整道测量精度要求,对既有线有砟轨道大机养道测量方法的改进和提高有一定的参考意义。
A new method of rapid and continuous measurement based on mobile RTK is proposed by comparing with the traditional method of ballasted track maintenance,aiming at the shortcomings of low efficiency and reliability of existing ballasted track maintenance measurement.Through field measurement experiments and track alignment simulation,it is verified that the new method can meet the requirements of measurement accuracy of existing ballasted track.It has certain reference significance for improving and measurement method of large maintenance of existing ballasted track.
