| 摘 要： | 郑州东站站房为全高架桥建合一铁路站房,其轨道层采用＂钢骨混凝土柱＋双向预应力混凝土框架梁＂的结构体系,首次将双向预应力混凝土框架结构应用于铁路桥梁。由于上部结构的矩形钢管混凝土柱要插入桥墩柱,框架梁采用双肋箱梁,显著减小了梁高及柱墩尺寸,避免了普通钢筋及预应力筋在穿柱时与上部钢柱埋入钢骨＂打架＂,保证了传力的可靠性。郑...

| Abstract: | East Zhengzhou Railway Station,a super-long span frame structure,is a combination of full elevated railway bridge and architecture structure.It is the first time to use a new type structural system in the railway bridge,including steel reinforced concrete columns,two-way prestressed concrete frame beams and cast-in-place concrete floors,which can improve economy and earthquake-resistance capability of the structure,reduce the size of components,and increase the architectural clearance and the usable floor a... |
