GPS在公路勘测中的应用,对高等级公路的勘测手段和作业方法产生了革命性的变革,极大地提高了勘测精度和勘测效率,特别是使需要分几道工序完成的作业合并成一次完成变成了现实,如中线测量的放线和中桩测设。文章介绍采用GPS、RTK和免棱镜全站仪相配合的技术方法在公路勘测设计中的应用,并对测量精度和应用中的问题进行了分析,提出了在公路勘测、施工和后期养护、运行管理方面的应用前景。
The application of GPS in the road survey has revolutionized the survey method and operation method of high-grade highways, greatly improving the survey accuracy and survey efficiency. In particular, the operations that need to be completed in several processes are merged into one complete Has become a reality, such as the midline measurement of the payline and pile survey. This article introduces the application of GPS, RTK and prism-free total station technology in the highway survey and design, and analyzes the measurement accuracy and the problems in the application, and puts forward the application in the highway survey, construction and post-maintenance, operation Management of the application prospects.
