Abstract:The transit-oriented development over a depot of a section of Shanghai rail transit line was taken as an engineering background to research the characteristics and difficulties of the public transit oriented development project. The first natural weak story of the depot caused by the process requirements were analyzed in detail, and the proper performance targets were put forward. It was suggested that structure preservation was needed in phased construction to solve the non-synchronous construction problem of top-side platform and depot. Finally, the top-side platform development project was summarized from the perspective of structural technology, and reasonable suggestions were put forward. The research results can provide some reference for the development of top-side platform over a depot.

Keywords:top-side platform over a depot; structure preservation; seismic performance
