Abstract: Research purposes: Hangzhou East Station is large and fully elevated passenger railway station featuring an integrated bridge and building structure， the design of the bridge structure will not only meet the railway load requirements，but also will be competent to carry the load from the building. This paper introduces the key techniques for the design of the bridge in the integrated bridge and construction. Research conclusions:(1) Hangzliou East Station adopts the concrete filled steel tube for pillar，and steel reinforced concrete for girder，which is reasonable and the component is reasonable and meet the requirements of the code. (2) As for the bridge and architecture unification， it is necessary to establish a whole model which contain both bridge and architecture construction to run the static calculation and analysis of vehicle bridge coupling. ( 3 ) Since the bridge of track bearing layer bears loads from bot!i the railway and the architecture，these loads should be combined according to the railway codes and the construction should be check - calculation on the basis of allowable stresses method. (4) The research conclusions can provide references for the similar structure in the future.
