| Abstract: | With doing the precise traversing network surveying of the Harbin metro line 1 in the third period,this pa-per elaborates the method to calculate ranging corrections,ranging error and angle measuring error. After checking the data,all the measurements comply with the technical requirements. And the rigorous adjustment of the control network is done,with the precision assessment after that. The final part proposes some experience and advice on how to improve the precision of the precise traversing. And it’s helpful for other metro projects as reference. |
