摘要
针对旧空腹式板拱桥结构安全性问题,以某旧空腹式板拱桥为工程实例,通过现场实测数据、外观检查及专项检查,利用有限元软件建立模型,进而参照相应的规范对旧空腹式板拱桥结构进行验算,验算结果表明原设计汽-20、挂-100满足现行规范设计公路-Ⅱ级,从而为桥梁养护部门对同类桥的维修加固做出合理决策提供科学的依据。
Combining with a project of the old hollow plate arch bridge,the article mainly aimed to make the analysis on the structure safety of the old hollow plate arch bridge by the field test,visual inspection and special inspection. In addition,the paper used the finite element software to establish the model and then did structure calculation according to the corresponding standard. The final result shows that the original design of steam- 20,hang- 100 meet the current specifications for highway- II level,which provides a scientific basis for bridge maintenance department to develop a reasonable reinforcement and conservation programs.
