Title: Preliminary Research on New Tubular Roof Method Used for Deeply Buried Underground Excavation Metro Station in Beijing Area
Abstract: Based on the background of the successful application of New Tubular Roof Method(NTR Method) in the construction of metro station in China,this paper describes the main steps of this method and analyzes its characteristics and advantages.Firstly,through analyzing the difficulties in the construction of deeply buried underground excavation metro station in Beijing area,this paper discusses the possibility of using the NTR Method in the water-rich quaternary system stratum in Beijing area.Further,by analyzing the applicability of the key techniques of some construction procedures,this paper proposes the research fields and tasks which should be carried out as soon as possible in the future.The paper thinks that: the NTR Method has some of scalability,which can serve as a scheme platform to carry out mutiple technical measures.And with this method,the station superstructure can be constructed in the same time when the shield machine tunneling through the station.So the NTR Method can be considered as a competitive method for constructing deeply buried underground excavation metro station in Beijing area.
