| 摘 要： | 针对GPS实时动态定位技术在铁路勘测中的应用，提出连续三角网重复设站测量既有线的方法。该方法以铁路控制测量的首级控制网点作为GPSRTK作业基准点，无需设置外移桩。数据处理时采用带约束条件的最小二乘法进行解算，可准确恢复既有线的各项参数，进而根据设计线形参数求得设计坐标，精确计算每一点的拨距量。 |
| 关 键 词： | 勘测 GPS RTK 既有线复测 线形参数 曲线整正 |

| Abstract: | A new surveying method with GPS RTK technique is proposed for the existing railway by overlapped stations in continuous triangle networks. Instead of making using of the traditional side stakes, the control points developed in rail construction are used as base station. In addition, a rigorous least square estimation algorithm is presented in which all linear parameters, designed coordinates and the accurate curve realinement corrections are obtained for each point related to the existing railway. |
| Keywords: | Survey GPS RTK Repetition survey of existing railway Linear parameter Curve realinement |
