摘　　要：文中以南昌某条市政道路下穿铁路专用线框架桥为工程实例,依据铁路规范对框架桥在顶进过程中便梁线路加固的桩顶荷载进行计算、组合,得出了起控制作用工况的桩顶荷载组合,计算了桩基竖向承载力,并简要阐述了桩基的验算内容。In this paper, a municipal road in Nanchang passes through a special railway frame bridge as an engineering example. According to the railway code, the pile top load of the beam line reinforcement during the jacking process of the frame bridge is calculated and combined, and the control engineering is obtained. The pile top load combination under the actual conditions, the vertical bearing capacity of the pile foundation is calculated, and the check calculation content of the pile foundation is briefly explained.
