    ENCOUNTERED ENGINEERING GEOLOGICAL PROBLEMS OF SHIELD TUNNELING IN BEIJING SUBWAY CONSTRUCTION

      Abstract
    • At present,Tunneling Boring Machines(TBMs)are extensively used to meet the demands for excavation of urban tunnels in Beijing,but many engineering problems were encountered during tunneling because of geological complexity.In this paper,based on the characteristics of the engineering geology and TBM excavations,the engineering geological problems in Beijing were discussed,and the relations between shield TBM excavations and the characteristics of the engineering geology were analyzed,from which TBM excavations should be better understood.
