Study On The Mechanism Of Main Disease And Reduction And Reinforcement Of Urban Viaduct

Due to The Belt and Road Initiative,xi'an underlines the importance in the national economic and political status,xi 'an city viaduct in the city road traffic transportation role more and more important?The urban viaduct maintenance and management requirements are more stringent and comprehensive,but it is not for xi'an city viaduct testing,disease treatment and related research,therefore,in this paper,based on xi 'an elevated wai village after fast trunk road overpass,detection of bridge condition to conduct a comprehensive investigation and disease characteristics analysis,system research based on the structure characteristics of the bridge structure stability,targeted bridge diseases treatment scheme is put forward,to determine the urban viaduct damage reason and enhance the scientific nature of the pavement maintenance scheme has very important practical significance.In this paper,the main work includes:(1)the bridge condition monitoring investigation and analysis of characteristics of diseaseWai village after a comprehensive understanding of xi an elevated fast trunk road overpass environmental characteristics,traffic characteristics and the bridge structure,on the basis of investigation of xi'an elevated wai village after fast trunk road overpass bridge disease condition testing and evaluation of the basic properties of the bridge.Mainly on bridge deck system,the structure of the upper structure,bearing,lower in the disease condition monitoring and other ancillary facilities.(2)based on the disease of bridge technical condition mechanism researchFor xi 'an elevated wai village after fast trunk road overpass technology condition,the bridge cracking situation,the deflection of beam body torsion,bearing damage,expansion joint damage and bridge pier displacement etc.Analyzed the causes of diseases,and puts forward the corresponding Suggestions.(3)the bridge reinforcement scheme and calculation analysisBridge test conditions for the second chapter and the third chapter of diseases.it analysis,put forward the proposals of the viaduct bridge reinforcement and construction procedure,and the bridge and the resistance to capsizing,bearing the basis,capping beam,pier and so on on the main mechanical index.(4)study on safety measures for the construction of Urban ViaductFor xi'an elevated fast trunk road wai village intersection line after reinforcement construction scheme,construction safety guarantee system of the relevant measures are put forward,in order to ensure the security of reinforcement construction made a great contribution.
