Passenger Dedicated Line Tunnels Engineering Deformation Monitoring Information Management And Forecasting System

As the first domestic railway line which is a total ballastless track, Wu-Guang passenger dedicated line is designed high in both speed and technique standard. The total length of tunnels is about 17% of the line. In order to realize the stability and safety of the track structure in the operation process, and ensure the operation quality, it is necessary to have a dynamic observation of underline engineering deformation. However, the dynamic observation has a long period and complicated and multiple data. To remedy the defects of the traditional observation, ensure the operation safety, and improve the economic benefit, it is important and significant to develop a tunnel underline engineering deformation monitoring system for information management and prediction.Relying on the Xichongzi tunnel of Wu-guang line, taking the guiding ideology of system engineering, on the basis of prediction theory, putting the software engineering technology as core, this thesis develops an information management and prediction system of tunnel underline engineering deformation monitoring. By applying the system, the thesis analyzes the data which are obtained in the deformation monitoring in the Xichongzi tunnel. The main work are as follows:(1) Through analysis and comparison, with the choice of statistic analysis model and grey prediction theory, the thesis fits the deformation time curve of the underline engineering deformation.(2) Developing a tunnel underline engineering deformation monitoring system to information management, it is convenient to operate field monitoring data, including the functions of data storage, query, modification, deletion, combination and automatic generation curve.(3) Developing an underline engineering deformation monitoring system to prediction, which is, transferring the prediction method to computer language, realizing the stylization, and what's more, on the relative data, selecting the best prediction model, so as to draw the prediction curve and predict the consolidation settlement.(4) Adopting various detecting methods, after monitoring the Xichongzi tunnel ballast, surrounding rock displacement of the tunnel bottom, and structure internal force separately, obtains the field monitoring data of a whole year, and then analyzing the data by adopting the software system, therefore, the maneuverability and stability of the system are verified.
