摘要 轨交地下车站普遍采用双跨或三跨的箱型结构形式,车站内部空间封闭且立柱较多。如何打造站台和站厅的空间通透感、提高乘客舒适度是工程设计中一项重要的课题。在上海轨交17号线某地下车站设计中,因地制宜地提出了顶、中板打开的隐柱式大中庭地下车站方案,从结构三维静力、抗震及施工工序3方面对该方案的结构关键点进行了论证研究,并通过顶板起拱的设计方案解决了站厅层20 m大跨结构受力的难题。 Rail transit underground stations generally adopt double-span or three-span box structure with closed internal spaces and many upright columns.How to realize spatial transparency of station platform and station hall and improve passenger comfort is an important subject of engineering design.During the design of a subway station of Shanghai Metro Line 17,the scheme of concealed-column,large-atrium subway platform with open top plate and intermediate plate is proposed in accordance with local conditions and the key structural nodes of the scheme pass feasibility study in three aspects including three-dimensional static force,earthquake resistance and construction procedure,thus addressing the problem of structural stress of 20 m large span on the station hall layer.
