Combining with the bearing replacement maintenance projects of the north approach of Jiangyin bridge,the SPLC-8 computer-controlled overall synchronous hydraulic jacking technology was used for bridge bearing replace-ment construction.The key problems of the overall synchronous construction without interruptting traffic,such as jacking control technology,lifting scheme and construction technology were discussed and analyzed.The results showed that the overall synchronous bridge bearing replacement without interruptting traffic by the SPLC-8 computer-controlled hydraulic jacking technology was feasible.
