RTK技术在铁路工程测量中的应用探析

Application of GPS-RTK Measurement Technology in Engineering Survey

现如今,我国铁路测量广泛运用电子全站仪等先进设备,但是,横向通视和作业条件大大制约了电子全站仪的作用。GPS-RTK技术是一种全新的、高效的动态测量模式,有着作业方法便捷、工作效率高、定位精准且误差累积少的特点。它还能全天候测量,可以大幅度减少测量工作量与工作人员,已被广泛运用到铁路工程测量中。论文从RTK定位与作业流程、工程概况、RTK测量方法与步骤、RTK实测中需要注意的问题等四个方面进行了阐述,以期为此项技术的进一步推广运用提出参考建议。

Nowadays, ETS（Electronic Total Station） has been used broadly in railway survey in China, but it has some disadvantages that the lateral visibility and operating conditions greatly restricts performance of ETS. Being a new and efficient dynamic measurement model, with the characteristics of convenient operation, high efficiency, real accuracy and less error accumulation,all-weather measurement, lower labour intensity and few workers, GPS-RTK measurement technology has been utilized in engineering survey. The article analyzes the following： GPS-RTK positioning and operation procedure, project overview, measurement method and process, and problems in measurement etc.. Based on the research, the author puts forward some reference proposals on application of GPS-RTK Measurement Technology.
