斜拉桥索梁锚固区的应力大小及分布是影响设计的关键因素。锚箱式索梁锚固结构中索力产生的附加弯矩对梁体受力的影响、以及通过减小弯矩来控制该区域应力的方法是否有效 ,是值得研究的问题。本文就南京长江第二大桥南汊大桥索梁锚固结构 ,对该问题进行了分析 ,结合有限元计算 ,得出了一些有益的结论 The stress distribution and the stress distribution in cable anchorage zone of cable-stayed bridge are the key factors affecting the design. Whether the additional bending moment caused by the cable force in the anchorage box girder anchorage structure has an effect on the bearing capacity of the beam and whether the method of controlling the stress in the area by reducing the bending moment is a question worthy of study. This paper analyzes the problem of cable-girder anchorage structure of Nanxun Bridge over the Second Nanjing Yangtze River Bridge. Some useful conclusions are drawn from the finite element analysis
