摘    要:采用大型通用有限元软件MIADSFEA进行空间计算,以磴口黄河特大桥为工程实例进行研究。用三维有限单元法对连续梁桥0号块作分析,对施工中0号块在最大悬臂状态下和成桥阶段的应力作计算,计算出各阶段0号块的应力状态,为优化设计和改进施工方法提供依据。对运营节段0号块在最不利荷载组合作用下的应力作计算,计算出0号块的应力状态。

关 键 词:连续梁桥  空间分析  0号块

Abstract:In this paper, Dengkou Yellow River bridge is a engineering example for research, by using the large-scale general finite element software MIADS FEA for spatial computation. The segment No. 0 is analyzed with 3D finite element method, and the continuous girder bridge segment No. 0 stress state in the maximum cantilever state and the bridge finished phase during the construction are calcu- lated which provides a basis for optimization design and improving construction method. And then the segment No. 0 stress state in the operation under the most unfavorable load combination are also calculated which provides reference for similar bridge design in the future.
Keywords:continuous girder bridge l segment No. O  spacial analysis
