英文摘要：

Basic composition of building isolation resistance to deformation device in mining area is introduced in this paper, and theoritical analysis of resistance to deformation isolation bearing was carried out based on earthquake engineering and mining subsidence principles. Through experiments, the hysteretic energy dissipation characteristicsthen of resistance to deformation isolation bearing of building in mining area subjected to low cyclic loading was analysed. Results show that the hysteresis energy dissipation curve of resistance to deformation isolation bearing is full and plump under low cyclic loading, which indicates its good self-reset, energy dissipation capacity, deformation capacity, stable hysteretic behavior and other characteristics, which also indicates its clear force transmission mechanism and reasonable structure. The isolation bearing full uses following three different kinds of energy dissipation material and energy dissipation mechanism： rubber bearing with lead core, viscous dampers and wing spring. Its appropriate level isolation stiffness and damping dissipation characteristics and its ability to resistance the uneven settlement in vertical direction fully reflect good overall stability. This resistance to deformation isolation bearing effectively improves building capacity of resistance to damage caused by coal mining and earthquake in mining area, therefore provides a scientific method and basis for building protection in mining areas.
