| The mountainous areas account for two-thirds of the entire territory of C hina, and the topography, geology, hydrology and other conditions are so complicated and diverse. As China’s economic developing, the western regional road construction has been in full swing, the region’s mountains, ravines, canyons and plateaus distributed more along the bridge construction is much greater. As the CFST upper deck arch bridge are always built in the mountains, which are just right for the area bridge tupe selection. So that type of bridge on bridge site selection and structure analysis study is very meaningful. The paper depends on Sulongzhu Yel ow River Bridge for the study, the main work includes the following aspects:(1)In this paper, the research status of the application and the status of research on the site CFST arch bridge position and made a review and summary of the system.(2)This paper focuses on the principle of bridge site selection, the impact of bridge site location factors and methods are summarized.Then the autor analyzes the influencing factors on CFST Arch Bridge Site and Method on Bridge Site. O n this basis, this paper research on the Sulongzhu Yel ow River Bridge for the study of bridge site selection.(3)Summarizing the calculation principles of steel concrete structure, single steel tube concrete compression member, the combination compression members, nodes, overall approach by the calculated force member, steel and concrete finite element modeling method for analog points.(4)research on the Sulongzhu Yellow River Bridge for the study of static, dynamic and stability analysis, and realistic simulation of the bridge construction process, the construction process of structure analysis.(5)Using of general-purpose finite element software ABAQUS segment under Soviet Pearl Arch Bridge steel effect the mechanical properties analysis, while the bottom chord K joint static fatigue properties and performance were analyzed and structure optimization. |
