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
