The current application status and existing problems of prefabricated technology for underground structures both at home and abroad were introduced.Taking construction of Pingxi Station on Shenzhen Metro Line 3 as the research object,a new prefabricated construction technology for underground metro stations under inner support system in a water-rich stratum was proposed.The structure was divided into blocks to design according to the load-bearing characteristics of a subway station without columns and road transportation requirements.The structural component connection joint method was adopted without expanding the joint,and the feasibility and rationality of the joint and section were analyzed through full-scale tests,when mechanical assembly equipment was also developed,which provides an important technical route for the mechanization,refinement and standardization of the underground prefabricated station construction under the inner support system.
