Abstract：Research purposes: As the construction of intercity railroad and high － speed passenger special railway，introducing railway hub into passenger dedicated line causes great influnces on urban land and people’s life． Because its demolition costs are not only doubled，but the demolition is difficult，time wasting and seriously affecting the engineering construction． Importing of Hefei － Wuhan railway into Wuhan hub causes parallel addition engineering． There are many high － rise buildings at one side of the addition engineering and lots of difficulties in extension and land expropriation project． So，C35 reinforced concrete frame － upstanding － hollow － shoulder retaining wall is designed．
Research conclusions: It contains retaining walls，culverts and bridge structural design in one system． The top of the wall surface，composed of rigid frame and sidewalk cantilever plate，meets the need of the layout of the station professional ancillary facilities． This structure design not only reflects the innovation and rationality of subgrade design，but also ensures the safety of existing lane and the existing building． After operation，its benefits of small footprint，wide bottom base，better itself stability，high level of resistance，and better anti － slide，anti － dumping effect，are fully reflected． But it also plays with the dual role of slope retaining and slopes receive． So，in the future，this design has the important reference value for the same type of railway roadbed engineering design and construction．
