        Abstract:        To evaluate the safety of a steel box bridge during the construction of a metro station, the process of excavation which was based on the metro station and its overpass bridge in Chengdu was analyzed. A detailed FE model was established which include the soil, the station and the bridge using general finite element software ALGOR. According to the procedure of the constructing station and completed station, investigating the absolute settlements and differential settlements of the earth's surface and foundation in metro station incidence, the effect on the steel box girder overall stress and local stress was analyzed extensively. The results demonstrated that the excavation has a insignificant influence on the deformations and stresses of the steel girder. Thus it provides an important understanding of the interactions of bridge structures and underground constructions. © (2013) Trans Tech Publications, Switzerland.
