The Research And Application Of A Tunnel Deformation Remote Monitoring System

Along with the construction of national infrastructure,roads and railways are gradually formed network,at the same time appeared the same than in mountain tunnel crossing,formed between tunnel and tunnel crossing,new roads or railway tunnel across or wear of existing tunnel under gradually increasing,in the construction of the new line,for not affect existing lines,required for existing lines in operation of the tunnel safety monitoring.Over the past few decades for the construction of the country,many tunnels also appear different degree of disease,need for existing lines in operation of the tunnel maintenance,to carry on the long-term monitoring,feedback the reliability of the reinforcement measures,etc.,does not affect the operation of the tunnel,and can always grasp the deformation of the tunnel,strengthening acquisition frequency,therefore,for existing lines in operation of the tunnel monitoring measurement put forward higher requirements.Traditional manual monitoring is no longer meet the requirements in the tunnel monitoring of operation,the need to find a can not only ensure the accuracy of monitoring,monitoring frequency,and does not affect the operation of the tunnel,remote automation monitoring method,relatively low cost.In this paper,we study the tunnel deformation monitoring the remote monitoring system,a kind of tunnel deformation and the chengdu-chongqing expressway passenger dedicated line in the new liangshan tunnel across both on line in liangshan tunnel deformation monitoring was carried out in field application,the effect is good,to guide the construction effectively,ensure that both the operation and the safety of the tunnel.To the current operation of tunnel safety monitoring technology research and development to provide the beneficial reference.This article is divided into five parts:The first chapter introduction elaborated the selected topic background and significance,research status at home and abroad are reviewed,the introduced in this paper,the research contents,research methods and research ideas,etc.The second chapter compares three methods of tunnel deformation monitoring analysis,by comparing the advantages and disadvantages of each system,developed a convergence deformation monitoring of tunnel deformation meter system based on laser remote monitoring system.The third chapter through indoor and field test,remote monitoring system for tunnel deformation work stability,reliability,testing,and to develop monitoring information database platform.The fourth chapter through the tunnel deformation and the remote monitoring system in actual application effects of the operating tunnel deformation monitoring,monitoring show that the system runs stable and reliable.The fifth chapter is conclusion and prospect.Through the research and development of a remote monitoring system of tunnel deformation,trying to solve the problem of automatic running tunnel deformation monitoring and timely feedback,effectively guide the on-site construction,ensure the safety of the operating tunnel,and the further operation of tunnel safety monitoring technology research is of great significance.
