| Abstract: |
Stonecutters Bridge is a cable-stayed bridge which will span the Rambler Channel in Hong Kong above the busy shipping channel. Construction commenced in early 2004 and the bridge is scheduled to be open to traffic in mid-2009. Steel deck segments in the main span are lifted from a dynamically positioned barge using lifting frames with high capacity winches to minimise the lifting time. Stay cables are the prefabricated parallel wire type, delivered to site on large reels. The unreeling and lifting procedures ensure the bending radius of the cables is kept above the minimum allowed. Stressing to predetermined installation length is by large hydraulic jack beneath deck level. Cable forces are calculated from the frequencies, measured by accelerometers. At the end of each erection cycle, surveys of the bridge geometry are compared with the predicted deflections for that stage and any adjustments calculated. Main span closure will follow towards the end of 2008. |
