摘要
为验证快速轨道测量系统在运营高铁无砟轨道测量应用的可靠性及可行性,基于某段高速铁路无砟轨道分别选用快速轨道测量系统GRP1000 IMS和常规轨道检测系统GRP1000,采用多点绝对设站的模式,按照设定方案进行轨道线型测量.综合对平面偏差、高程偏差、轨距、超高偏差、轨向和长短波等轨道参数进行对比分析,结果显示利用快速轨道测量系统可以大幅度提高无砟轨道线型测量效率,且能满足高速铁路无砟轨道线型测量精度要求.
Abstract
In order to verify the reliability and feasibility of the application of the rapid track measurement system in the measurement of the ballastless track of the high-speed railway in operation,based on the ballastless track of a high-speed railway,the rapid track measure-ment system GRP1000 IMS and the conventional track detection system GRP1000 are selected respectively,and the track alignment measure-ment is carried out according to the set scheme by using the mode of multi-point absolute station setting. The track parameters such as plane deviation,elevation deviation,gauge,super-high deviation,track direction and long-short wave are compared and analyzed. The results show that the use of fast track measurement system can greatly improve the efficiency of ballastless track profile measurement,and can meet the re-quirements of high-speed railway ballastless track profile measurement accuracy.
