| Abstract: | Tian An Men East Station of Beijing Metro has been constructed by the cover and excavation top-down method with beam foundation under columns. The pith and marrow of this method is the combination of both the traditional "cover and excavation up-down method" and the "shallow tunnelling method", the latter is used: for constructing beam foundation. The new method has the merits of less disturbance to surroundings and shorter construction period, it is especially suitable for construction of large scale underground project in the downtown district. The construction process and monitoring measurements of this engineering project are mainly introduced in the paper. |
