精密导线测量在广州地铁二号线北延段的应用

The application of precise traverse measurement in the northern extended section of line No.2 in Guangzhou subway

通过精密导线测量在广州地铁二号线北延段中的应用,详细地介绍了精密导线网的设计、精密导线的外业观测及数据处理、对精密导线的测量精度进行了评定,比较了联测二号线的控制点坐标,对今后广州轨道交通工程的精密导线测量提供了较好范例。

Through the application of precise traverse measurement in the northern extended section of line No. 2 in Guangzhou subway, the article introduces the design of precise traverse network, field observation of precise traverse and data processing, evaluates the measuring accuracy of precise traverse, and compares the control point coordinate of line No. 2 by co-measurement, in order to offer a well reference for further precise traverse measurement of rail transit engineering in Guangzhou.
