GPS-RTK技术在高速铁路工程测量中的应用
摘要:随着我国经济的高速发展,高速铁路也随之发展迅猛,因此对于高速铁路的工程测量要求越来越高。近年来,高速铁路已经采用了很多电子设备及技术,但是由于受到作业条件的现实限制性问题,这些电子设备及技术在工程项目中很难应用,因此,GPS-RTK技术得到广泛应用。GPS-RTK技术具有很多优势,比如,定位精度较高,工作效率高,作业方法简单,误差累积较少等,越来越受到工程的青睐。目前,铁路中线测设、控制测量、开口线放样、断面复测等都需要应用GPS-RTK技术。

Abstract: with the rapid development of China's economy, high-speed railway is developing rapidly, so the demands for high speed railway engineering surveying is getting higher and higher. In recent years, high-speed rail has adopted a lot of electronic equipment and technology, but due to the reality of operation condition restricted problem, these electronic equipment and the technology is difficult to application in engineering projects, as a result, the GPS - RTK technology is widely used. GPS - RTK technology has many advantages, such as high positioning accuracy, high efficiency, operation method is simple, less error accumulation and so on, more and more get the favour of engineering. At present, the railway line layout, control, measurement, open layout, section survey and so on all need applying GPS - RTK technology.

当测量长线铁路工程时,受到现实条件的限制,比如:工程项目通视条件差、通行条件不良,使得之前的电子设备及技术便显出了很多缺点,比如:工作量大、精度不能达到指标、定位不精确,不能达到工程项目的要求,而GPS-RTK技术以其精确、快速、实时性良好占据了很大优势。
