In this paper, the characteristics and seismic performance of precast concrete structures are expounded. The research progress of seismic isolation technology in precast concrete structures is introduced in recent years, including base isolation system, seismic isolation system, Damper and so on. In view of the effectiveness of seismic isolation technology in improving the seismic performance of structures, the application of the technology in precast concrete structures at home and abroad is summarized. The future development of seismic isolation technology of precast concrete structures is also discussed. In view of the shortages of seismic isolation technology in improving the seismic performance of precast concrete structures, it is pointed out that the theory of multi-dimensional seismic isolation of precast concrete structures and the research and development of new seismic isolation devices are the main contents that need further study in the future.
