| Abstract: | In steel structure of cast-in-place concrete box arch bridge, the stress assumed by steel arch can be reduced due to arch combined effect by using sub-ring construction method. Through the large software AN- SYSIO simulation and the measured data analysis, this paper studies the combination effect between arch ring and arch centering, and analyzes the stability of steel arch. |

| Keywords: | box arch bridge sub-ring segmented construction arch centering combined effect stability |
