Study On Loading Test Scheme Of Caiyuanba Yangtze River Bridge, Chongqing

With the progress of science and technology, the fundamental changes emerged in the design method and design theory of bridge structure.And yet, there are a lot of factors affect the quality of a project. For building up engineering quality, people expect to finding and grappling its behavior and effection. In this case, people verify the design theory and calculative method, assess the loading ability, examine construction qualit and usage condition and etc whether it meets the demand of design and standard by means of loading test.The bridge load test based on applicating direct loading in bridge structure, and then through the tests,Records and study, including test arranging,theoretical calculation,and test in field and the result analysis etc. In this way, finding out bridge structure's working state under action of testing loads, and more evaluating bridge structure workmanship and bridge operating condition, providing a scientific basis of final acceptance and exploration.Main task in the thesis:1,To build the finite element model of caiyuanba Yangtze river bridge by the software midas;2,Calculating theoretical inner force under action of design load and test loading;.3,Measurating key section's strain,deflection,influence lines of internal force,time-history curves for vehicle loads to pass through and offer initial state's data for long term structural health monitoring;4,Giving dead load testing program,loading position,load mode capacity tonnage of caiyuanba Yangtze river bridge.5,Giving dynamic load testing program,loading position.
