Application of cross-joint technology in metro depot based on seismic isolation technology
A design scheme of cross-seam of metro depot based on seismic isolation technology is proposed.Through isolation conversion,the overhead structure of metro depot can be developed,which effectively avoids the limitation of overhead structure caused by the overhead seam.Setting the isolation transfer layer at the top of the depot and adjusting the layout and parameters of the isolation bearings can meet the deformation requirements caused by temperature and earthquake when the cover structure crosses the crack under the cover,so as to ensure the safety and use of the structure.Based on a metro depot project in Shanghai,the research and analysis of the proposed cross-seam technical scheme shows that the cross-seam layout of the cover structure can be realized by adopting the isolation conversion method,which makes the layout of the cover building more flexible,and is con-ducive to the high-quality development of the cover building in the metro depot.
