Summary:Structural deformations of the existing metro station caused by adjacent building construction should be controlled strictly so as to keep the normal operation of the existing metro station and guarantee the safety of the station structure. Based on a foundation pit excavation and building project which is adjacent to an existing metro station in Beijing, a 3D finite element model of foundation pit, metro station and surrounding soil is established. Then, the structural deformations of the main body structure (rail area), the passageway and the fire fighting passageway in different construction stages are obtained. The control values of the station structure deformation during building construction process are proposed according to the calculation results.
