摘要：
Combined with the geological conditions and the project's features of Beijing subway station, in order to solve the selection problem of pilot tunnel's construction method in undermining the station, directing at the commonly used method-CD method, CRD method and double side wall pilot tunnel method, we can adopt FLAC3D numerical calculation method in controlling its surface deformation effect and supporting structure hand features to make analysis and prediction, then we can conclude the surface settlement's size and law and analyse the feasibility of these methods in this section and the differences of various method, make effective election of these methods by comparation.
