Abstract: The present disclosure discloses a self-reset flexible earthquake-resistant system of the prefabricated subway station, comprising prefabricated component prestressed tendon, waterproof rubber, and rubber bearing. The main structure of station is built by connection between prestressed tendon and prefabricated component, it changes the connection methods of connection node from consolidation joint to hinged joint which makes the subway station into a flexible system, while at the same time, self-reset function is realized by prestressed tendon; “T” and “” system is combined with rubber waterproof tape, and rubber bearing which is installed in connection site of prefabricated component, multi-protection measures of waterproof is realized, earthquake-resistant effect is also realized. Connection problem with the prefabricated component can be solved by the self-reset flexible earthquake-resistant system of the prefabricated subway station; underground station structure is changed into the flexible system through releasing bending moment in connection site of the prefabricated component, deforming ability of subway station is improved, the earthquake-resistant ability of underground subway station is improved.
