Design, Production and Erection of Full Span Pre-tensioned Pre-stressed Concrete Box-Girders in Incheon Bridge Viaduct

摘要

The objective of this study is to represent the design and construction of pre-stressed concrete (PSC) box-girders in Incheon Bridge Viaduct. The superstructure of the viaduct was planned and designed to be made by pre-tensioned pre-stressing method in a specially built casting factory, transported to the construction field at sea, and erected by FSLM(Full Span Launching Method), using specially developed methods and equipment. In this paper, key items of analysis and design of PSC box-girders are introduced. Also, brief construction method and sequences are represented.
