Single-column double-longitudinal-beam subway structure
The invention belongs to the technical field of metro engineering, and relates to a single-column double-longitudinal-beam metro structure which comprises a top plate, a middle plate, a bottom plate and side walls, the top plate, the middle plate and the bottom plate are sequentially erected between the two side walls from top to bottom and form a frame type structure with the side walls, at least two top longitudinal beams are distributed on the top plate at intervals, and the top longitudinal beams are arranged on the middle plate. The top longitudinal beams are longitudinally arranged along a subway line, every two adjacent top longitudinal beams are connected through an upper arch structure, and the upper arch structures are connected with the bottom plate through supporting columns. Double columns are changed into a single column, the width of a subway structure is reduced, the plate thickness and reinforcement of a top plate and a bottom plate are reduced, good economic benefits are achieved, the arrangement of the flat arch structure is adopted, the compression performance of concrete is fully utilized, the structural stress requirement is guaranteed, and the clear height requirement of a station hall layer and a platform layer is met.
本发明属于地铁工程技术领域，涉及一种单柱双纵梁地铁结构，包括顶板、中板、底板和侧墙，所述顶板、中板、底板由上至下顺次架设在两个所述侧墙之间，并与所述侧墙构成框架式结构，在所述顶板上间隔布设有至少两个顶纵梁，所述顶纵梁沿着地铁线路纵向布设，相邻的两个顶纵梁之间通过上坦拱结构连接，所述上坦拱结构通过支撑柱与底板连接。本发明由双柱改为单柱，减小地铁结构宽度，减小顶板和底板的板厚和配筋，具有很好的经济效益，采用坦拱结构的设置，充分利用了混凝土的受压性能，既保证了结构受力要求，也满足了站厅层与站台层的净高要求。
