Analysis Of Steel Truss Arch Bridge Construction Project In Jining South Second Ring

In recent years, with the further development of our country city rail and high-speed railway construction, rapid development of economy, there will be more and more long span bridges with steel truss arch structure. Jining South Second Ring across Beijing-Hangzhou the Grande Canale main bridge superstructure design for three span continuous steel truss arch bridge, the main span of360m. The bridge traffic powerful, landscape effect is obvious, but the complexity of the construction process, according to the design characteristics and construction conditions, safe and reliable, economical and reasonable formulation, construction scheme feasible, is of great significance to the construction of similar bridge engineering.In this paper the Jining South Second Ring across Beijing-Hangzhou the Grande Canale steel truss arch bridge in non-stress closure and construction method, mainly to solve the following problems:1, Through the plan comparison, selection of Benxi Iron and steel truss arch bridge whole construction method and construction scheme.2, Through the simulation analysis, to determine the control parameters and main factors affecting the internal forces and deformation and component structure, formulate corresponding construction measures and quality assurance measures, maximum limit reduces the risk of the construction process, saving the construction cost.3,Temporary structure calculation and the improvement of the construction process.By comparison, the simulation analysis, further optimize the organic combination of site construction plan, determine and implement the construction scheme of steel truss arch bridge, reduced the construction risk, improve the construction efficiency, save construction costs, achieved good economic benefits, accumulated experience for the construction of the similar Bridges...
