Abstract:The jacking-up replacement test of the bearing of an isolation structure was introduced,  including the internal force analysis of the main structure,  the prediction of the deformation difference,  the jacking-up of the structure,  the replacement and installation of the bearing. The jacking-up scheme adopted asynchronous jacking-up method,  and the design and key technologies of asynchronous jacking-up method were introduced including arrangement of force transmission device and jacking-up machine and the vertical displacement control system in asynchronous jacking-up method. And the economic analysis was carried out on asynchronous jacking-up method.

Keywords:isolation; bearing replacement; asynchronous jacking up; economic analysis
