Abstract

This paper presents the analysis results to evaluate the application of separation sleeper boot of turnout in concrete track in subway. An analysis includes the dynamic load on turnout-bridge and the ballast improvement method of upbound and down line independent girder in servicing line. From the results, the aspect and the property of separation sleeper boot of turnout are evaluated. FE analysis explain the relationship between independent bridge and track behaviour of dynamic loads. The assessment of application based on FE analysis results in a good improvement method of servicing subway line is proposed.
