| Abstract: | The jacking construction plan of a tunnel bridge of large slender ratio is presented in this paper. A detailed Finite Element Method model is created. The structural behaviors subjected to several load cases during jacking construction stage are analyzed. Based on the FEM analysis results, sensors are mounted. Monitored data are used to ensure the safety of the tunnel bridge during jacking construction stage. Some suggestions are given for similar structures. |
