| 摘 要： | 以重庆东水门长江大桥为研究对象,采用Midas Civil大型桥梁分析软件进行建模,研究辅助墩位置的变化对新型索辅梁桥成桥状态的主塔、牛腿处下弦杆、主梁的影响。计算结果表明,增加辅助墩后,索辅梁桥的主塔塔底弯矩、塔顶纵向位移、主梁跨中轴力、跨中挠度都有所减小,牛腿处下弦杆的弯矩增大。

| Abstract: | A three-dimensional finite element calculation model was established for the main bridge of the Dongshuimen Yangtze River Bridge in Chongqing by using software MIDAS Civil.It was obtained that different positions of the auxiliary pier exerted influence on the main tower,the bottom chord on the bracket,the main girder in the bridge completion state of the new partially cable-supported girder bridge.The calculation results demonstrated that increase of auxiliary piers would lead to bending moment of the lower... |
