| Abstract: | Tower top cable saddle of Right Branch Main Bridge in Jiangxin Island of Nanjing Yangtze River Tunnel Project has a pre-bias in the main span before main cable is erected, which will be gradually pushed to the designed position in the system conversion. We successfully completed the main cable saddle pushing through accurate estimation of the pushing force and rational design of the reaction frame. |
