Abstract

The curved beam bridge is widely used in modern city viaduct． Because the complexity of its space stress mechanism，diseases are often found in curved beam bridge which could harm structural safety and serviceability． For this reason，such sort of bridge should be repaired． In this paper，some repair schemes were compared via finite element analysis based on a real bridge project． It is decided that synchronous jack-up system should be used for this project． This system has many advantages，especially when it is used in curved beam bridge． It was discussed the feasibility of using the system for repairing curved bridge project，based on the analysis of synchronous jack-up systems construction process，construction system，correction and bearing-replacement operation process． Through the analysis of monitoring data，the usability of this system was demonstrated in this kind of engineering project． In the end，some recommendations were put forward for popularizing．
- synchronous jack-up system,
- curved beam,
- correction of curved beam,
- besupport-replacement
