Abstract：
This paper summarized the domestic and international application of prefabricated technology on subway engineering. It includes open-cut subway Station and entrance prefabricated component, blanket system prefabricated component by the cover-excavation method, tunnel prefabricated lining by the subsurface excavation method, pre-fabricated beams of elevated railway, precast pavement, assembled steel structure temporary works etc. Analysis indicated that, it is feasible that prefabricated technology use in subway project. Prefabricated technology has reliable quality and efficient assembling. It cost savings and has lower the material consumption. It is energy efficient and environment friendly. It has little impact on environment and many advantages to improving the working environment. Economic benefits, environmental benefits and social benefits are obvious.
