Analysis Of The Overall Stability Of Curved And Ramp Bridge

Curved and Ramp Bridge played in the rapid development of urban and road construction in the high-speed pivotal role, but the relative lack of specific norms and overall domestic bridge overturning accidents, so the overall stability of the slope curved bridge needs adequate attention. In this paper, project examples for the study, using finite element analysis software Midas Civil, highway bridges and culverts for the new specification(draft) "(JTG D62-2012), to overturn stability coefficient bridge superstructure analysis. Also studied the influence of the car live loads on the overall stability of the slope of the bridge curved bridge and superstructure of consolidation. Specific work is as follows:â‘  through engineering examples summarized curved slope bridge during operations common diseases, and for different factors recommendations;â‘¡ introduced two different seat layout principles Polar layout principles and tangent layout principles, with the finite element software analyzes the influencing factors of the two seat arrangement;â‘¢ for the new highway bridge specification(draft) "(JTG D62-2012), the definition of the upper structure of overturning axis curved slope of the bridge need to be perfected, and verify the accuracy of the stability factor against overturning calculation;â‘£ the upper structure of the pier and consolidation in the form of curved slope using the bridge, by setting the vehicle load partial load, overload and pier eccentricity parameter variables to analyze the impact on the overall automobile live load curve slope stability of the bridge, the bridge is similar The design and operational management to provide a reference.
