Wuhan-Guangzhou Passenger Line is the first railway line , across the board Ballastless track design speed is fast , high technical standards , the total length of the tunnel accounted for 17% of the entire line . Dynamic observation of the deformation of the tunnel line works to achieve stability and security of the structure of the high-speed railway line in the operating process to ensure the quality of operations , long cycle of monitoring , data and more . In order to make up for the deficiencies of the traditional method of data processing , research and development of information management and forecast system of deformation monitoring economic efficiency is important for ensuring the Passenger Dedicated run security and improve the passenger dedicated line . In this paper, fine Punch Tunnel of Wuhan-Guangzhou Passenger Line relying on systems engineering as the guiding ideology , to predict based on the theory , as the core software engineering , the development of the Passenger Line tunnel line engineering deformation monitoring information management and forecast system , and use of systems engineering deformation monitoring under fine punch tunnel line data analysis and validation , the main tasks include the following : ( 1 ) by analyzing and comparing the choice of statistical analysis model and gray prediction theory passenger Line tunnel line engineering the deformation time curve fitting . ( 2 ) R \u0026 D the Passenger Line tunnel line engineering deformation monitoring information management system to facilitate the operation of the on-site monitoring data , including data storage , query , modify , delete , merge , and automatically generate the curve function . ( 3 ) R \u0026 D engineering deformation prediction the Passenger Line tunnel line , upcoming forecast compiled computer language , procedures , and selected the best predictive model based on the correlation coefficient , which draw the predicted curve to predict deformation and subsidence ; ( 4) using a variety of monitoring methods were fine punch tunnel Road bed surface tunnels at the bottom of the surrounding rock displacement and internal force of monitoring , obtain up to 1 year of on-site monitoring data , and the use of a software system developed on-site the measured data were analyzed to verify the operability and stability of the system .
