暗挖车站采用新构筑法设计方案

以沈阳地铁10号线东北大马路站暗挖段为例，提出了一种新的暗挖施工方法一新构筑法。该施工方法通过引入大直径钢管混凝土支护体系，在车站覆土及断面形式均与明（盖）挖车站相当的情况下实现暗挖施工，是对传统暗挖施工方法的重大改进。对该施工方法的设计方案进行了详细的论述，并通过计算分析对设计方案进行验证。该施工方法可避免暗挖端厅车站的出现，具有广泛的应用前景。

New Method of Underground Excavation for Metro Station

Taking the bored section for Northeast Road station for Shenyang metro line 10 for example, the paper puts forward New Construction Method. The method introducing a large-diameter steel tube for support system, in the form of both the station covering and section casing and open cut （cover） station construction excavation, this is a big improvement for traditional underground excavation method. The designs scheme of the construction methods are in detailed discussion, and the calculation and analysis have verified. The construction method can avoid the station excavation for side hall.
