Abstract:Research purposes : China is a large country,and the geological condition is very complex,railway tunnels quantity under construction is many,mostly in northeast,northwest, southeast and southwest mountainous area,traffic conditions is extremely inconvenient. Combined with China s national conditions,at present most of the railway tunnel excavation by drilling and blasting method,mechanization degree is not high,at the same time,the specialization degree of technical personnel,management personnel and workers is not relatively high, the tunnel construction safety risk is extremely high. For tunnel construction safety, the existing monitoring of the surrounding rock mainly uses the level, convergence meter,total station. In essence,it is difficult to break through the 11 artificial reading,manual calculation, paper to fill in" model, the problems of 11 frequent interference factors, slow data processing, obstructed feedback" often occur in the implementation. Therefore, it is necessary to information research and management on the railway tunnel surrounding rock monitoring.
Research conclusions:(1) Railway tunnel surrounding rock monitoring CFC information system consists of the three modules of the acquisition and transmission, analysis and release and treatment of closed loop. By the eight steps of 11 code entry ~> measuring point embedding~> data acquisition~^data transmission~> analysis and release~> information read ~^ site disposal ~^ closed loop", the information management is implemented. (2) Railway tunnel surrounding rock monitoring CFC information system has the characteristics of 11 reliable data, transmission efficiency,simple management, reasonable fees". The system basically realizes the railway tunnel surrounding rock monitoring management,and has a good application effect. (3) The research results can be used in tunnel surrounding rock deformation monitoring and safety management.
