Abstract: The covering top-down method can be better applied to large urban underground construction in city downtown areas, which is inverse in construction under the covering conditions. The design scheme for deep excavation of Pingleyuan Station of Beijing Metro line No. 14 is introduced. The stress characteristics, selection principles, design points of horizontal and vertical systems of the excavation are discussed. Some key problems are also analyzed. It may provide reference for similar projects.
