以獐河沟拱桥为研究对象,采用大型通用有限元软件ANSYS建立全桥有限元模型,在成桥状态下,选取10种工况进行静力学分析,并进行模态分析。为验证计算结果的合理性,选取42个拱肋应变测点和12个挠度测点,对该桥进行成桥静载试验,并进行动载试验。结果表明有限元分析结果与试验测试结果吻合较好,同时试验结果表明桥梁结构强度和刚度满足设计及规范要求。 Taking Zhanghegou Arch Bridge as the research object, a large-scale finite element software ANSYS was used to establish a full-bridge finite element model. Under the bridge condition, 10 kinds of working conditions were selected for static analysis and modal analysis. In order to verify the rationality of the calculation results, 42 arch-rib strain measuring points and 12 deflection measuring points were selected and the bridge was subjected to static load test and dynamic load test. The results show that the results of finite element analysis agree well with the experimental results, and the experimental results show that the strength and stiffness of the bridge structure meet the design and specification requirements.
