摘要
针对局部锚梁支架稳定性问题,基于支架结构稳定性基本理论建立了锚梁支架局部结构的有限元模型。根据有限元模拟结果,考虑悬索桥结构受力非线性问题,分别对东岸、西岸和主梁支架结构应力进行了模拟计算,对不同部位的支架进行了屈曲稳定性、整体及局部稳定性和地基承载力分析。研究结果对类似非对称式自锚式悬索桥的施工控制理论与实践研究具有一定的应用价值。
As for the stability of the local anchor beam support, based on the basic theory of the stability of support structure, the local structure finite element model of the anchor beam support was established in this paper.According to the finite element simulation results, considering the nonlinear behavior of the suspension bridge structure, the support structure stress of the east bank, west bank and main beam were calculated respectively.Moreover, the anchor beam support stability, overall and local stability and foundation bearing capacity of different parts were analyzed.It can provide certain application value for the construction control theory and practical research of similar asymmetrical self-anchored suspension bridges.
