RESEARCH ON CONSTRUCTION TECHNOLOGY OF RAMP BRIDGE ON SUBWAY
When building subway lines in cities,they often face complex terrain and traffic environment.The research on construction technology of ramp bridge is aimed at solving technical problems in subway line construction under complex urban environment,improving construction quality and efficiency,and ensuring normal operation of subway lines.In order to ensure the safety of ramp bridge,it is necessary to strictly control the construction quality and simplify the construction procedure as much as possible.Combined with a metro project in a city,this paper analyzes the overall prestressed tensioning construction technology of the on-ramp bridge in the metro car depot,focusing on three aspects:the deepening design procedure of prestressed construction,the friction test of prestressed pore and the key technology of prestressed construction,aiming to provide useful reference for the construction of the same type of projects.
