Research conclusions: Based on the analysis of the Ranjiaba Station with the three － dimension model，the design method for the stress reinforcement in the transfer node region is offered． According to the load － bearing characteristics of the plate thickness of the transfer node，the double － plate arrangement mode is presented．According the load － bearing situation of the middle column，the scheme of the steel section concrete column is given． Based on the simulation analysis of TBM passing the station，the scheme of bearing the TBM load with the rail － mounted middle plater by temporary support and bearing the structure load by the permanent load － bearing structure is pointed out．
