某地铁车站半盖挖法设计研究

Case Study on Design of Semi Cover and Cut Construction of Metro Station

为在狭窄的城市道路空间快速进行施工,并尽可能多地提供市政道路交通,结合黄忠路口站提出结构顶板半盖挖的施工方法。在比较以往地铁车站利用临时便桥结构盖挖的基础上,通过设计方案比选,对半盖挖结构主要工况作受力计算,并对半盖挖设计方案作综合研究和详述分析。结果表明,在城市地铁建设中结构顶板半盖挖法在城市交通、提高施工进度等方面切实可行,具有一定的社会和经济效益。

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.
