| Abstract: | This paper systematically summarizes the technical innovations in upgrading track smoothness of Shenzhen Metro Line 9 as follows:laying a double block sleeper with a truss,using new smooth railroad turnouts and roller sliding plate system,laying prefabricated floating slabs,using rail-based control network measurement techniques (CPⅢ),etc.They can solve the problems and deficiencies that the traditional cast steel spring floating slabs brought to the subway system so to provide sufficient technical reserves,greatly improve the track laying accuracy and smoothness,and reduce the maintenance work during the operation. |
