| 摘 要： | 以某采用贯通锚固方式的矮塔斜拉桥为背景工程,为了解该类型矮塔斜拉桥桥塔受力特点,明确桥塔受力中局部危险区域的分布,建立了该斜拉桥桥塔的空间有限元数值模拟分析模型,按照等效简化荷载及边界条件对其进行加载分析。分析表明,该背景工程矮塔斜拉桥索塔拉索区局部应力水平合理。

| Abstract: | A practical cable-stayed bridge is presented in this paper,in which pass through anchor type is adopted.For researching the basic force-bearing characteristics of extradosed RSC bridge cable tower in segments with cables and identifying the distribution of partial risk regions,3-D finite element model is established with specially equivalent and simplified loads and boundary conditions.Research results show that local stress of tower segments with cables in this low-tower cable-stayed bridge is rational. |
