客运专线无碴轨道精密定轨测量方法及精度分析

摘要

客运专线无碴轨道精密定轨测量采用智能型全站仪,并在全站仪中加载专用的数据采集软件,完成数据的自动采集、自动记录和自动检核等任务.测量结束后,通过专用的数据处理软件进行数据的平差处理及其精度分析.文中以客运专线无碴轨道CPIII后方交会控制网为基础,对全站仪自由重叠设站的精密定轨测量技术进行理论研究和误差分析,对小车棱镜点测量方法和测量精度进行分析.%Ballastless track in the passenger dedicated railway line is surveyed by intelligent total station, in which a dedicated data acquisition software is loaded to complete the data collection, automatic recording and automatic inspection of data and other tasks. A dedicated data processing software for data analysis of the adjustment process and its accuracy serves after surveying. Based on free overlap positioning with total station actively for passenger ballastless track CPIII control network, the first is to set up the theoretical research and error analysis, and the second is to analyze the car prism point surveying method and precision.
