Inspection And Reinforcement Technology Application Of Rigid Frame Arch Bridge

The social economy construction developing led to zhe rapid development of bridge engineering,along with the road traffic volume and vehicle load increasing,a lot of bridges have varying degrees of damage,which has become a potential hazard of transportation development.With its advantages of good appearance,low cost and maintenance cost,rigid frame arch bridge is widely used and occupying a big proportion of the number,but due to the long construction time and its poor stability,potential bearing limitations,a large number of diseases of rigid frame arch bridge appear in the use phase.How to transform and reinforce the rigid frame arch bridges is imminent.Firstly,this thesis analyzes the development of inspection and reinforcement technology of the rigid frame arch bridge,besides,it introduces the inspection technology,evaluation methods,structure composition,key points of inspection,common diseases and common reinforcement methods of this type of bridge.Then through a specific engineering example,using MIDAS Civil 2015 and MIDAS FEA 3.6 software to establish the finite element model to analysis this type of bridge,the paper analysis the results of inspection,technical condition evaluation,Load test and causes of disease.puts forward the specific reinforcement plan,and puts forward the requirements in strengthening construction process,construction technology,materials and environmental protection.Finally,this paper evaluates the bridge reinforcement effect,which has great significance to promote the analysis of the structure optimization and the reinforcement scheme,providing reference for further research and engineering practice of the inspection and reinforcement technology of rigid frame arch bridge.
