Abstract: Semi cover and cut method is proposed for the construction of Huangzhonglukou station, which is located under busy urban roads. The loading conditions of the structures constructed by semi cover and cut method are calculated and comprehensive study is made on the design of the Metro station to be constructed by semi cover and cut method. The results show that the semi cover and cut method is feasible in relieving the urban traffic difficulty and improving the construction speed. 

Key words: Metro station, semicover bottomup cut method, structural roof slab, 3D calculation
