Research On The Construction Deformation Monitoring Of Surrounding Rock And Geological Forecast In Changchong Tunnel

Based on the Chongqing Nanfu ChangChong highway tunnel,the paper analyzed and summarized the modes, methods and data processing of the Monitoring of tunnel from the wall rock deformation theory, simply introduced and compared the main methods of the geological forecast for highway tunnel. The paper then analyzed of the sensitivity of the displacement to parameters and researched the methods of data regression and information feedback of the monitoring projects by relying on the basis of the measurement processing,provided more reliable information for numerical calculating about face analysis than the other's; analyzed and compared the functions of displacement data regression and choosed the most suitable, put forward the research methods of the load release laws of the space effect. Then, through the application of the examples, the theories put forward above have been verified. At the end the paper, conclusions have been given, which also contained the inadequacies and the main direction of future research. These research may have some reference values in the future engineering practice and other research.
