Study on the Auto-total Station System for Monitoring Analyzing and Forecasting Tunnel Country Rock Deformation

This paper discusses the principle, function, development and application of the system comprising a total station and a computer for monitoring and analyzing tunnel country rock deformation , presents the new methods of two free stations of 3D measurement, and single station and two free station independent coordinate measuring-lines as well as their concerning mathematic adjustment models. Design and development of the total station software on-board and post data processing software are also described. Under the control of the software on-board , the total station can fulfill all measurements to target points automatically whereas there is no need to center the equipment and measure its height, The monitoring data can be processed by the post software of the computer and the regression analysis and forecasting information of the tunnel country rock deformation can be provided in time for tunnel construction.
