GPS在高速公路平面控制测量中的应用研究

Research on the application of GPS in highway plane control survey

近些年,我国经济发展增速趋于稳定,人们生活水平稳步提高。但经济发展是建立在有良好基础设施建设的前提下,其中修建高速公路是一项必须进行的工程,公路测量者需要根据数据拟定一个建设方案,使得该工程高效率、高质量的完成,为保证高速公路建设工程高质量完成,需要建立完善的控制网,其中使用GPS定位功能辅助建立平面控制网是常见的方法,本文重点介绍静态GPS定位和控制网设计,并详细分析GPS定位技术在公路平面控制测量误差的运用,其中重点分析了如何选取投影面和投影带,为高速公路建设提供帮助。

In recent years, China＇ s economic growth tends to be stable, people＇ s living standard is improving , but the economic development is based on a good infrastructure. The construction of the expressway is necessary engineering. Measurement needs according to the data to develop a construction project to the complete the project of high efficiency and high the quality. In order to ensure quality, we need to establish a perfect control network, including the establishment of plane control network using GPS positioning function is a common auxiliary method, this paper focuses on the static GPS positioning and control network design and analysis the application of GPS positioning technology in highway construction plane control network. Projection plane and projection zone selection were analyzed, We hope to provide help for highway construction.
