The Analysis And Research On Highway Tunnel GPS Control And Deformation Monitoring

As the rapid development of transportation, application of tunnel construction increasingly in China. Tunnel construction control, construction safety get the attention of researchers increasingly.this pape relying on Daliu highway tunnel project as an example,to research the GPS control survey highway tunnel and the deformation monitoring tunnel hole section.In the GPS control survey highway tunnel, we combined with tunnel project control measurement requirements and GPS control measurement features to analyzed GPS control measurement principle, GPS plane control network layont and observation, and combination of Daowushan tunnel GPS control survey projects to analyzed spotting selection, within the field data collection, data processing and possession of adjustment, and to analyzed the accuracy of GPS data , achieved good results. According to GPS elevation control nets, using level elevation measurement and GPS elevation for analysis, and combination of Daowushan tunnel projects to using five different schemes are fitting precision and quality analysis, achieved good results.Generally,highway tunnel hole section deformation is bigger then other place. According to the characteristics of the surrounding rock tunnel hole section, we come up with effective monitoring method and established the hole section wallrock deformation datum and monitoring system,To ensure the hole section construction stability and security. In monitoring methods, mainly introduced the surface and hole deformation observation, peripheral convergence, vault sink, surface subsidence monitoring technology and settlement standards etc . And the data processing theory were introduced. Combined with the Yitaiwan tunnel hole section of monitoring method, monitor examples benchmark, data processing and settlement of the implementation of the regression forecast for detailed instructions and research.This paper, which carry out the construction of road tunnel control and detection technology to provide reference deformation。...
