摘要
对某钢管混凝土拱桥不同的稳定性设计方案进行了介绍,利用有限元方法对钢管拱施工、成桥各阶段的整体稳定性进行了空间分析,并讨论了影响整体稳定性的因素,希望通过比选找出最佳的稳定性方案。
The design feature of a CFST arch bridge with different plans of stability is introduced.The stability of the bridge during and after constructing was analyzed with finite element method.The factors affecting the stability of bridge were discussed in order to find optimum design for structure stability.
