摘　　要：以某座连续刚构桥为例,采用Midas FEA空间有限元分析软件,对加载模式1和加载模式2下的0号块结构进行了空间应力对比分析,同时对加载模式2进行了建模优化。研究结果表明,加载模式1和优化后的加载模式2均能作为精确分析实体模型空间应力的有效加载方法,同时也对两种加载模式各自的优缺点进行了总结,为今后类似实体结构的建模加载方法提供参考。Based on a continuous rigid frame bridge,using Midas FEA spatial finite element analysis software to conduct the comparative analysis of the spatial stress of block zero under load mode 1 and load mode 2,and the model of load mode 2 is optimized.The research results show that load mode 1 and optimized load mode 2 are effective loading methods for accurately analyzing the spatial stress of the entity model.The advantages and disadvantages of the two load modes are summarized,providing a reference for modeling and loading methods of similar entity structures.
