Analysis and Research of Reinforcing and Increasing Bearing Capacity of Rigid-frame Arch Bridge by Synthesis including Increasing Section Technique

The research method and process about reinforcing and increasing bearing capacity of rigid-frame arch bridge by increasing section technique are introduced.After the project was established,the group of project gathered relevant information and made systematic analysis of reinforcing technology for rigid-frame arch bridge with the on-the-spot result of survey,and accordingly put forward the reinforcing design of synthesis by increasing section.After a month,the design was carried into execution,the bridge has been reinforced and its bearing capacity has been increased effectively.According th the result of experiment,the effect of design is remarkable.
