Analysis and Research on Construction-monitoring Technology for Long-span Prestressed Continuous Girder Bridge
In the process of infrastructure construction,long-span prestressed continuous girder bridges are widely used to cross valleys and rivers,and the construction safety and stability of long-span prestressed continuous girder bridges have always been the problems that need special attention in the construction process.The construction technology of continuous girder bridge is complicated,and many system changes are involved in the construction process,which affects many parameters.In order to ensure the safety and quality of continuous beam bridge construction,it is necessary to establish a reasonable and correct monitoring and control system.This paper takes a continuous girder bridge as the main research object,and uses MIDAS/Civil finite element software to carry out in-depth research on the construction safety and stability of continuous girder bridge,and guides the on-site construction,line monitoring and stress monitoring.Through the numerical theoretical calculation of the bridge and the analysis and comparison of the field measurement data,some valuable research results and opinions are put forward,which can be used for reference by the monitoring personnel of similar bridge projects.
