According to the actual situation of high-formwork engineering and large deformation monitoring in Guangzhou subway, this paper studies the new method of monitoring based on measuring the deformation of a robot, that is a mixed base-point network method and multi-point & compulsory free-station linear-angular intersection method, and it was successfully applied to a number of typical projects. Practice has proved that the method is both simple with high degree automation. At the same time, monitoring accuracy can meet the requirements of a variety of typical deformation warning works.

Keywords:Georobot, Mixed Base-Point Network, Multipoint Compulsory Free Station, Linear-Angular Intersection Method, Automated Deformation Measurement System
