Structure Stress Analysis For Integral Abutment Bridge

Along with the rapid development of economic construction and road traffic load level increases, traditional bridge damage because of the expansion device broken causing is a widespread phenomenon, seriously impact the traffic running. Integral abutment bridge is a jointless bridge, as cancelled expansion device and achieved continuous deck, as well has reduced the incidence of disease, Earthquake Disaster Mitigation and advantages of quick construction schedule. Therefore, many foreign scholars as well as inland do a great deal of research for integral abutment bridge.However, there are many unsolved and uncosummate problems in the aspects of analytical methods and design for integral abutment bridge, especially the temperature difference in the cold areas was big, and the research for the integral abutment bridge was at the blank stage. Therefore, the combination of characteristics of cold regions, on the integral abutment bridge further research is necessary, with the actual value. This paper conducted the following studies:(1) Combined with the overall structure of the bridge abutment, and design overpass over rich industrial park, propose some advice for the design of integral abutment and bridge through analyzing the characteristics of integral abutment and bridge during the process of design;(2) Though the comparative analysis of internal force distributionfor considered replaced the pile length by the calculation model and the righe pile length by the calculation model.(3) Through the back soil, Earth level constraints different simulation method calculates the results of the comparison analysis, explored the whole heating loads fall soil and Earth level constraints of rational calculation method, presented a reasonable soil and Earth level calculation method of resistance...
