Underground three-layer large-span column-free station structure
The invention provides an underground three-layer large-span column-free station structure, and belongs to the field of underground structure engineering of urban rail transit and municipal engineering. A top plate and a bottom plate are arched with uniform section thickness, a middle plate is reinforced by adopting flat plates with uniform thickness and haunch angles, and a side wall adopts a vertical section with uniform thickness, so that vertical columns are not arranged in a stress system of an open-cut three-layer station main structure, the structural form of longitudinal beams of each layer is canceled, and the open-cut three-layer station main structure is successfully applied in actual engineering. According to the structure, equipment and facilities in a station are flexibly arranged, the space in the station is fully utilized, and the scale of the station is effectively reduced; and on the premise that the structural safety of the station is guaranteed, the structural stress characteristic is improved, the structural size and arrangement are optimized, additional anti-floating measures of the station are reduced, the construction steps are reduced, the construction quality is guaranteed, the engineering investment is saved, and good application prospects and popularization values are achieved.
本发明提供一种地下三层大跨度无柱车站结构，属于城市轨道交通、市政工程地下结构工程领域；其通过顶、底板设置等截面厚度起拱，中板采用等厚度平板及腋角加强，侧墙采用竖向等厚截面形式，实现了明挖三层车站主体结构受力体系内不设竖向立柱、取消各层纵梁结构形式，并在实际工程中得到成功应用；本发明的结构使车站内部设备设施布置更灵活，站内空间得到更充分利用，有效减小了车站规模；在保证车站结构安全下，改善了结构受力特性，优化了结构尺寸及布置，减少了车站附加抗浮措施，减少了施工步序，保证了施工质量，节约了工程投资，具有较好的应用前景和推广价值。
