Reinforcement Method And Effect Analysis Of Prestressed Concrete Continuous Rigid Frame Bridge

With the rapid development of science and technology,and the wide use of high-strength materials, as well as the emergence of advanced construction methods and construction equipment, prestressed concrete continuous rigid frame bridge has been the rapid development in the 20th century 90's.Because the increasing number of construction,and increasing span,as well as increasing pressure on the continuous improvement of operations.Therefore,these are many new topics to the prestressed concrete continuous rigid frame bridge maintenance reinforcement.Among them, the reinforcement method and reinforcement effect of theprestressed concrete continuous rigid frame bridge are the important factor in the development and further development of Prestressed concrete continuous rigid frame bridge reinforcement. continuously improve the level of simulation technology of prestressed concrete continuous rigid frame bridge strengthening to rational choice the method of reinforcement and analysis results of reinforcement,the project will have a tremendous value and cost-effective.The first,this article introduced the Situation and commonly used method of reinforcement,the Second,this article introduced the design of continuous rigid frame bridge reinforcement. Finalthis article use the model to analyze the effect of reinforcement.The determine of reasonable state and rational construction is the key to bridge construction process simulation.In this paper, the construction process from top to bottom flange girder bridge stress and bridge deflection are the main control goals.to analysis the changes in stress and deflectionof of control location.To determine the reasonableness of model,and on the basis of strengthening the state after the bridge checked to determine the effect of reinforcement.This paper, an anhui bridge as the background, use the Midas / Cvil finite element software to establish a full-bridge model,and according to the state of the continuous process gradually improve the model and calculate.after the completion of reinforcement to determine the overall effect of the bridge.Anyway,the large number of prestressed concrete continuous rigid frame bridge is one type of the bridge that assume currently carrying capacity,so,it is a very important work to analysis the existence disease,to extend its service life with effective methods of strengthening the bridge,to ued the limited construction of much-needed funds for the current project,and this is also a new great help for future of our country new prestressed concrete continuous rigid frame bridge.
