摘　　要：利用通用有限元程序ANSYS对怀洪新河特大桥主塔鞍座锚固区应力进行了空间受力分析，从而得出了该桥不同区域应力分布情况，并针对存在隐患部位提出了相应建议，为索鞍设计提供了理论依据，对同类矮塔斜拉桥的应力分析具有一定指导意义。The paper undertakes the space stress analysis of the saddle anchorage zone of main tower of Huaihongxinhe super-large Bridge by adopting the general finite element program ANSYS, concludes the stress distribution of the bridge in different areas, and points out the respective suggestions for the hidden parts, so as to provide theory basis for saddle design and have certain significance for the stress analysis of the similar cable bridge of short towers.

关 键 词：斜拉桥 鞍座锚固区 局部应力分析
