Accuracy Analysis of Non-Prism Total Station Measurement Technology in the Monitoring and Measurement of Railway Tunnels
In the construction process,measurement is an indispensable part.Traditional measurement uses a prism cooperatively,it not only sets up a total station,but also selects a point to set up the prism,and it measures the dis-tance and the angle through the reflection between the total station and the prism,which takes a lot of time.Non-prism measurement technology is not the same,which does not have strict requirements for reflectors,and stones,walls and metal bodies at the target location can reflect signals.In the monitoring and measurement of railway tun-nels,the construction team lays steel bars and places reflectors as targets,and instruments can be directly used for measurment after they are set up,saving a lot of time.
