随着社会经济发展的越来越快和人民生活水平的日益提高,城市与城市之间、城市与乡村之间以及乡村与乡村之间的经济、政治、文化交流往来越来越频繁,这在一定程度上促进了道路交通业的发展。在一些地形较为复杂的地区,常常需要对山体进行挖掘,形成隧道供车辆通行,一般的隧道测量采用三角测量方法或者精密导线测量方法,这些传统的测量方法具有局限性,常常受到地形条件、通视条件的影响,也即在对隧道进行观察测量和选择合适的地点布置控制网络是非常困难的。在此通过对全球定位系统这一技术的介绍和对隧道测量的现状的分析,阐述全球定位系统在隧道测量中的应用方法,从而促进全球定位系统在隧道测量中的应用,为施工单位更准确地进行隧道测量、保证隧道建设的高质量尽一点绵薄之力。
With the accelerating social and economic development and the ever-increasing standard of living of people, economic, political and cultural exchanges between cities and cities, between cities and villages, and between rural areas and rural areas have become more frequent To a certain extent, promoted the development of road transport industry. In some complex terrain areas, it is often necessary to excavate the mountain to form a tunnel for vehicles to pass through. Generally, tunnel measurement uses triangulation methods or precision wire measurement methods. These traditional measurement methods have limitations and are often subject to topographical conditions, Depending on the condition, that is, it is very difficult to observe and measure the tunnel and select the appropriate location for the control network. Through the introduction of the technology of GPS and the analysis of the status quo of tunnel surveys, the application of GPS in tunnel surveying is expounded here, so as to promote the application of GPS in tunnel surveying and make it more accurate for construction units Tunnel measurement to ensure the high quality of the tunnel construction to make a modest contribution.
