Research On Detection And Reinforcement Techniques For Reinforced Concrete Double-curvature Arch Bridge

With the rapid development of bridge engineering construction in our country,the bridge structure form and function have become increasingly complex,after long-term use,all kinds of bridge structure damage bound to occur,so the bridge detection and reinforcement technique have become the important guarantee of bridge structure safety and normal use,also more and more attention by all of us.Therefore,in order to fight better maintenance and use of active bridge,the study and analysis of bridge detection and reinforcement technology is very necessary.This article has the research about detection and reinforcement technology only for arch bridge.Due to the complexity of bridge structure,first in this paper,the use of this kind of bridge status quo,structure,key parts of test,the common diseases and common reinforcement methods are introduced.Then it lists the engineering example,through one specific engineering example,to explained the detection method,content,technique condition evaluation results and pertinence reinforcement method of diseases about Hyperbolic arch bridge also have the construction process,material,construction technology of the bridge reinforcement.Finally,this paper analyzes the internal force of the reinforced structure and verifies the feasibility of the reinforcement scheme.In this paper,some suggests for the detection and reinforcement technique of Hyperbolic arch bridge are proposed,so that the detection and reinforcement work can be done better in order to play a role in the subsequent detection and reinforcement of similar bridges,the design and calculation of the old bridge design and calculation theory Inspection methods and reinforcement maintenance to provide reference data in the future.
