Abstract:

This paper presents analysis and construction method of the Sorok (self-anchored suspension) bridge that is currently under construction in the Sorok Island, CheonllaNamdo, Korea and expected to be completed in 2008. To find the optimum initial equilibrium condition of self- anchored suspension bridge, the force of main cable and hanger are developed together with minimizing vertical camber of stiffening girder. Erection stage analyses are carried out for both hanger-pulling method and girder jack-down method to find out the more effective one which ensure the erection stability and cost efficiency. Hanger-pulling method is adopted as the erection scheme of suspension system as a result of the study. Various measurement results at site show that analysis results are well matched up with bridge deformation and girder profile during construction and at ist final stage and have a good correspondence with the original design profile
