运营地铁隧道修复中碳纤维布的应用

CFRP has been widely applied in all fields of civil engineering. In recent years it has been brought in operational subway tunnel segment repairing in Shanghai and other soft soil area. In this paper, segment repairing in one of Shanghai Metro Line No. 1 Running Tunnels is used as the basis. The reinforcement principle of CFRP is introduced, and construction technology and points of CFRP in segment repairing are summarized in detail. All of these can offer reference for the subway tunnel segment repairing, the reinforcement makes a summary of the technology in the subway. Application prospect of CFRP in subway tunnel and other underground engineering is prospected.
