The Analysis Study Of Single Tower Suspension Bridge Structural Parameters Impact

When we build long-span and large-span bridges,we always used suspensionbridges.In Chongqing,there is good geological conditions.It is suitable for theconstruction of Suspension Bridge.Yangtze River Bridge on Cuntan single towersuspension bridge anchored to the tender program analysis and understanding. Singletower suspension bridge on the carrying capacity to do a certain amount of calculationand analysis.First, this paper describes the history and development of current developmentSuspension Bridge. Comparative advantages and disadvantages of self-anchoredsuspension bridge, due to construction of complex. Therefore proposed to single towersuspension bridge anchored in the Chongqing region banquet more advantageous.Secondly, I gave a introduction of the suspension of static analysis theory.Itincluded the theory of elasticity, deflection theory and nonlinear finite displacementtheory and the classical theory.Then, illustrates some basic information Cuntan Yangtze River Bridge, roughlyProject Background Cuntan Yangtze River Bridge, the project location, the maintechnical standards, the need for construction and construction goals for the areatendering projects know the conditions of the overall design, the design of the bridgeproject plan, and finally to Chongqing Yangtze River Bridge Cuntan original single towersuspension bridge bidding program as the basis, the finite element model, focusing onanalysis of single tower suspension bridge under static load bearing capacity of anddeformation, to explore the construction of single tower suspension bridge is reasonable.Then, change the parameters of the ground-anchored suspension bridge, its towermoment, the main cable axial force, the main cable deformation, deformation boom,stiffening beam deformation impact. This chapter examines the impact of changing theparameters of the whole suspension bridge bearing capacity to bottom section of themoment, while the cable axial force, the main cable cross-section of the verticaldeformation of the object of study, were hanging suspension bridge span ratio changing,high-span ratio, the main tower high, analysis and comparison of its impact on thesuspension bridge carrying capacity. Finally,I gave a new of the Yangtze River Bridge Cuntan single tower suspensionbridge anchored to correct the program.I used the introduction of new parameters tocheck and analysis.And making the single tower suspension bridge with a morereasonable form.
