| 摘 要： | 通州玉带河大桥主桥为四跨三塔双索面预应力混凝土矮塔斜拉桥,主桥孔跨为45 m+85 m+85 m+45 m。由于拉索锚固区受力极为复杂,会产生较大的局部应力,该文应用ANSYS程序采用三维空间实体单元对锚固区在最大索力的情况下进行应力分析计算,并根据结果给出了相关的设计建议。

| Abstract: | The main bridge on Yudai River of Tongzhou is 4-span 3-pylon double-plane pre-stressed concrete low-pylon cable-stayed bridge.The spans of the main bridge are 45m+85 m+ 85m+45m.The larger partial stress will be produced because of the most complicated stress in the cable anchorage area.The article applies ANSYS program and three-dimensional space solid to analyze and calculate the stress of anchorage area under the condition of maximum cable force,and gives the relative design suggestion on the result. |
