The Dilute Single-plane Cable Stayed Bridge Stability Analysis Of The Construction Process And To Bridge

As China’s economy continues to develop, transportation construction has alsobeen a corresponding rapid development. Cable-stayed bridge across the river at thesame time as the river is very competitive bridge, has also been rapid development, withincreased span cable-stayed bridge, tower and cantilever construction phase alsoincreases, cable tension increases, all these have led to an increase in the stability of therisk cable-stayed bridge. Therefore, the stability study of cable-stayed bridgeconstruction phase and the operational phase of the static force will become increasinglyimportant.With the increasing emphasis on the environment, aesthetics and other factors, butalso the emergence of new forms of cable-stayed structure of many. Which dilute singlecable plane cable stayed bridge also homeopathy and health. Watergate East RiverBridge is a single cable plane cable to dilute featured across the top of the Yangtze River.This thesis is this bridge engineering background, dilute single cable plane cable stayedbridge stability of the corresponding research, completed the following correspondingwork:①Stability analysis for cable-stayed bridge theory expounded;②Relying on the actual Watergate East River Bridge project, using the finiteelement software for all construction and operational phases conditions static conditionWatergate East River Bridge simulation analysis；③Static stability analysis by finite element software on the construction andoperational phases of the typical conditions East Water Gate Bridge each typicalworking conditions, has been the stability of the various stages of the appropriate safetyfactor, and that analysis of the stability of the various stages of the bridge；④Wind loads applied to each condition, the effect of wind loads on each phasestability of the bridge;⑤Typical operating conditions for the operational phase of the nonlinear stabilityanalysis, correlation coefficients security and stability, while the elastic stage staticstability results for the relevant comparative analysis；⑥Through the above results of the static stability, and other structures in the formof cable-stayed static stability associated comparative analysis done；⑦By analyzing the results, the dilute single cable plane cable stayed bridge static stability and draw relevant conclusions proposed cable-stayed bridge in the futuredevelopment of relevant comments.
