摘　　要：以乌鲁木齐市城市轨道交通试验段控制网建设为重点,综合考虑1号线控制网建设,从试验段和1号线区域的地形、不同投影面的选择、投影变形等方面出发,采用大地测量技术,利用已有控制点资料,进行区域每公里综合变形值计算分析。同时考虑与已有重合控制点坐标值对比,提出合适的试验段控制网坐标系。结合实际应用,进行了验证,建立了与1号线控制统筹考虑,满足施工需要,和城市坐标系建立了联系的轨道交通试验段控制网坐标系。Focus on building the control network of Urumqi urban rail transit test section ,and consider building the control network of the line No .1 Comprehensively .Base on the terrain ,the choice of projection ,the distortion of projec-tion and other aspects of the test section and the line No .1,we used the geodetic surveying technology and existing con-trol points to compute and analyze the comprehensive distortion values of the area per kilometer ,and then ,compared with the coordinates of existing control points ,built a suitable control network coordinate system of the test section ,and tested it in practice.Finally,base on computing and analysis ,we built a satisfied control network coordinate system of the rail transit test section ,which is considered with the control of the line No .1 and combined with urban coordinate system .
