地铁车站盖挖逆作复合墙结构设计与分析

Design and Analysis of Composite Wall Structure of Diguni-axial Cover of Subway Station

结合某地铁车站结构设计过程,分析了车站主体盖挖逆作施工过程中的主要外荷载作用,提出了地铁车站盖挖逆作复合墙结构计算模型,详细介绍了盖挖逆作复合墙结构的设计计算要点,并通过有限元软件对施工过程结构最不利状态进行了结构内力计算。对同类工程设计具有一定的参考价值。

On the basis of design structure of a subway station,this paper analyses the main external load during construction of dig uni-axial cover,and introduces the model for composite wall structure and its design details.Using finite-element software to calculate internal force under the worst condition,it has certain reference value for similar projects.
