Abstract：Research purposes: It is not rational in the span and linear for Viaduct in station area limited by railway，site，landscape and so on． With design of bridge component limited，bridges in station area are often designed as single support curved girder，which has more risk of overturning． This paper based on the analysis of the West Railway Station in Tianjin，studied the relevant measures to improve its stability and ensure the safety of viaduct in station area and the coordination of landscape．
Research conclusions: After a targeted analysis，through spatial models established by the finite element method，the data shows that spatial models can truly simulate the forcing property of single support curved girder bridges． And it also shows that，the appropriate choice of pier beam consolidation measures can effectively reduce the risk of overturning， and reasonable eccentricity of structure can improve the stability and security of different structures． It may provide reference in bridges of the same structure．
