| 摘 要： | 由于槽形箱梁铁路桥的空间受力情况较为复杂,为此建立新长沙站大桥空间实体模型,分析各种荷载工况下箱梁各个腹板的剪力分配情况,用以指导箱梁的抗剪设计;同时通过计算分析箱梁的空间应力分布情况,提出横向分缝的构造处理措施,以避免槽形梁梁顶以上腹板应力过大。

| Abstract: | Because spatial stress characteristic of railway channel beam is rather complicated, this paper built up the spatial model of New Changsha station railway beam, and analyzed shear distribution ratio of every beam web under different load case to guide the shear design. Moreover the paper calculated and analyzed the spatial stress distribution of channel beam, and presented transversal structure dividing in order to avoid excessive stress of the web above the channel beam. |

| Keywords: | channel beam shear distribution stress distribution structural dividing |
