1、RTK 技术在公路测量中的应用RTK technology in the Highway Survey总计 毕业设计（论文） 15 页表 格 0 个插 图 4 幅I摘摘 要要20世纪90年代以来，GPS全球定位系统在应用领域的研究取得了迅速进展。测绘行业 首先将GPS应用于大地测量，并进一步将该项技术推广到工程测量之中。目前动态测量实 时定位的GPS载波相位差分技术(简称RTK定位技术，Rcal Time Kinemadc)已经被广泛应 用，RTK定位技术就是基于载波相位观测值的实时动态定位技术，它能够实时地提供测站 点在指定坐标系统中的三维定位结果，并达到厘米级精度，其已在施工放样实践中成功
2、 应用。 在公路勘浏中，RTK技术与传统的测量方法相比，具有以下明显的特点： GPS定位精 度高而且不受环境和距离长短的限制，非常适合地形条件复杂、互不通视的地区；GPS 高精度的高程测量，是GPS测量应用的重要领域；GPS RTK技术将完全改变公路测量模式， 它能实时得到所要点的空间三维坐标，很适合线路、桥梁、隧道等工程的勘测并可直 接进行实地实时放样、中桩测量和点位测量基础； GPS测量可大大提高了工作效和成果 质量，为测量自动化、数字化打下了坚实的基础，同时也极大地降低了劳动强度，减少 了野外砍伐工作量。大大提高了生产作业效率。但是由于卫星它在遇到高大建筑物或树 时，就很难接收到卫星和无
3、线电信号，也就无法进行测，所以在那种情况下我们又要用 到全站仪配合RTK来进行道路横断的测量和道路中线的放样，大大加大了工作的效率。关键词：关键词：GPSGPS RTKRTK 技术，道路横断面测量，道路中线放样技术，道路横断面测量，道路中线放样AbstractIIAbstractSince the 90s of the 20th century, GPS global positioning system in the application of research in the field has made rapid progress.

4、ustry first applied geodesy, and further extended to the engineering survey of the technology into. Currently real- time dynamic measurements of GPS Carrier Phase Positioning technology (referred to as RTK positioning technology, Rcal Time Kinemadc) has been widely used, RTK carrier phase positionin
5、g technology is based on observations of real-time dynamic positioning technology, it can provide real-time measurement site in the specified coordinate system in three-dimensional positioning results, and to achieve centimeter-level accuracy, which has been in the construction setting practice succ
6、essfully. Survey visit of the road, RTK technology with traditional measurement methods, has the following distinctive features: GPS positioning accuracy. And distances from the environment and the restrictions, very suitable for complex terrain conditions, each region Sight; GPS precise leveling, G
7、PS measurement applications is an important area; GPS RTK technology will completely change the road measurement mode, it immediately obtain the three-dimensional coordinates of points of space, it is suitable for lines, bridges, tunnels and other works of the investigation. Setting field Shi Shi an
8、d directly, in the measurement and point level measurement of pile foundation; GPS measurements can greatly improve work efficiency and quality of the outcome, for the measurement automation, digital has laid a solid foundation, but also greatly reduce the labor intensity, reduced the field cut down
9、 the workload. Greatly increased the efficiency of production operations. However, due to tall buildings in case of satellite it is or tree, it is difficult to receive satellite and radio signals will not be able to test, so in that case we have to use Total Station with RTK to road cross-sectional
