Abstract:

 The interinfluence between the tunnels constructed by shield machine and the opencut subway station supported by pile and anchor cable is elaborated in this paper. Some difficulties and the countermeasures in such construction in recent years are also presented. The station pit is supported by the bored piles and prestress anchor cables， which can ensure the safety during construction of deep excavation， but the anchor cables in the soil enter the scope of the shield tunnel that can prevent the boring of the shield machine. The anchor cables with removed core are used to solve the difficult problem， which can also be applied to other similar constructions.

Key words: shield method  , prestress anchor cable in soil anchor cable with removed core
