摘要
针对恩施凤凰大桥各施工阶段的特点,建立有限元分析模型进行了稳定性分析。根据分析结果提出了施工过程中应注意的问题,并采取相应的措施以满足安全性要求。
Stability of the Fenghuang Bridge in construction stage is analyzed in this paper. Considering the complexity of the construction procedures, which is decided by the diversification of the arch cross section and boundary, linearity and nonlinearity stability are analyzed based on the finite element model. Some available conclusions and suggestions are drawn for the construction stage.
