三维定位系统用来观测轨面高程(高低)、横距(线路方向)和纵距(钢轨纵向位移)位置的变化,通过分析测量点数值变化,及时发现线路三维变化情况。本文介绍了三维精确定位系统的建立和应用,在既有提速线路上用于线路的精确养护维修,适用性较好。
The three-dimensional positioning system is used to observe the changes of the position of elevation (height), horizontal distance (direction of the line) and longitudinal distance (longitudinal displacement of the rail). By analyzing the change of measurement points, the three-dimensional changes of the line can be found in time. This article introduces the establishment and application of 3D precise positioning system, and it is used in precise maintenance and repair of lines in existing speed-raising lines, which has good applicability.
