摘　　要：本文以吴忠黄河大桥为例,对混凝土连续梁桥悬臂施工阶段进行空间应力分析研究,建立有限元模型,运用ANSYS分析梁体的力学行为,为实际桥梁的设计和施工提供一定的参考。With the Wuzhong Yellow-River Bridge as an example, a space-stress analysis of the pre-stressed concrete continuous bridge at the cantilever construction stage is made. In this paper, the finite element model is established too, and the finite element analysis program, ANSYS is used to analyze the structure behavior of the pre-stressed concrete continuous bridge, the result of which may serve as a reference for the design or construction of actual bridges.
