客运专线精密定轨测量方法研究

A Study of the Method of Precise Track Determination Survey of Passenger Dedicated Railway

以客运专线精密定轨CPIII"自由设站边角交会"平面控制网为基础,对高速铁路无碴轨道精密定轨测量技术进行分析研究。文中首先对全站仪自由重叠设站精密定轨测量技术进行理论研究和误差分析,然后对小车棱镜点测量方法和测量精度进行分析。这对于目前客运专线和无碴轨道城际铁路的精密定轨测量具有一定的指导意义。

Based on the horizontal control survey network of the precise track determination of passenger dedicated railway according to the CPIII principle of ＂Free stationing and linear angular intersection＂, this paper analyzes and studies the technique of precise track determination survey of high speed open track railway. It studies the technique and analyzes the error of precise track determination surveying using total station equipment free overlapping stationing method, and analyzes the survey method and accuracy of car prism point surveying method, which is significant in the precise track determination survey of the current passenger dedicated railway and open track intercity railway.
