| 摘 要： | 以国内某新建城际铁路连续梁拱桥铰座为例,对铰座部件进行了建立在接触理论上的受力分析,并建立Ansys有限元实体受力模型,进一步分析铰座竖转受力特征。结论表明:在最不利工况下铰座强度能够满足规范要求;有限元分析证实受力计算结果,工程实践证明采用接触理论开展同类型工程设计是可行的。

| Abstract: | Based on the free bearing of a newly built intercity railway continuous beam arch bridge,the stress of free breaing elements is analyzed with contact theory,and a Ansys solid mechanical model is established to further analyze hinged support under vertical turning stress. The conclusion shows that the strength of the free breaing meets the design requirement under the most unfavorable load,and the stress calculation results are identical to finite element analysis. The engineering practices demonstrate that it is practical to use contact theory for similar project design. |
