Static Load Test And Finite Element Analysis Of Multi Span Prestressed Bridge

Bridge load test as a bridge carrying capacity assessment and structural testing of the technical means,more and more attention.The load test is mainly to evaluate the normal operation capacity,the surplus bearing capacity and the local structure strength of the bridge structure,which is of great significance to the bridge construction technology data,the accumulation of the old bridge test data and the assessment of the bridge grade.It is of great theoretical and engineering application value to carry out the load test and to evaluate and analyze the bridge.In this paper,a large bridge load test is used as the engineering background.Based on the results of the static load test and test data of the bridge,the finite element software Midas Civil is used to analyze and calculate the different parts of the bridge.The main work is as follows:1、According to the characteristics of load test,the development trend of bridge load test and bridge assessment is described synthetically.2、the comprehensive analysis of the bridge load test steps,focusing on the experimental steps in the note and the role.3、the background of the static load test site layout and test content,the test conditions for detailed division,so that the bridge static load test results more accurate and effective.4、Based on the importance of the bridge load assessment test and the preparation of the test and the precautions,the factors influencing the evaluation results of the load test are analyzed.Taking the static load test report of the background engineering as an example,the results of the static load test The static load test shows that the static structure of the bridge structure is good and conforms to the specification.The research content of this paper can provide some reference for the load test and bearing capacity evaluation report of the bridge,and also provide some theoretical basis for the future development of the project specification.
