摘要
独塔不对称斜拉桥由于边主跨相差较大,理想的成桥状态较难确定。根据设计经验,边跨设置辅助墩对这类斜拉桥的受力性能有显著的改善作用[1]。借助大型有限元通用计算软件MIDAS CIVIL,结合某PC独塔不对称斜拉桥实例,计算分析了辅助墩对独塔不对称斜拉桥的受力性能影响,为同类斜拉桥的设计提供参考。
It is hard to make sure the ideal completion of single-pylon asymmetric cable-stayed bridge because of the greater difference between its main and side spans. Based on the design experience, the auxiliary pier constructed for the side span has the obvious improvement effect on the stress performance of this kind of cable-stayed bridge. With the help of the large finite element current computation software MIDAS CIVIL and combined with a practical example of PC single-pylon asymmetric cable-stayed bridge, the article computes and analyzes the influence of auxiliary pier on stress performance of single-pylon asymmetric cable-stayed bridge, which can be referred for the design of the similar cable-stayed bridges.
