| Abstract: | Using an exemplified project,the article introduces a method to establish the reference network for deformation monitoring under relatively difficult working conditions.This method does not use known controlled points,but consider the relative fixed points as known points,and use the three points intersection method to establish an absolute coordinates system approximate with the local coordinates system to monitor the tube deformation. |

| Keywords: | deformation monitoring coordinates system total station three points intersection |
