| 摘 要： | 以一座矮塔斜拉桥为研究对象,采用空间有限元方法计算了索鞍的受力情况,将索力比较真实地转化为抛物线形面压力施加在各个对应孔道上,并分析了孔道施工偏差对运营阶段塔的影响。

| Abstract: | Based on the design drawings of low tower cable-stayed bridges,the paper discusses the different stress effect on the tower saddle under different load case by using the space FEM.By transforming the cable force into actual parabolic pressure on the corresponding hole area the analysis can reflect more accurate result,and also analyzes the tower's deflection due to the construction error. |
