| 摘 要： | 结合一座矮塔斜拉桥设计、整体计算情况，为研究骑跨式索鞍局部受力状况，采用三维有限元软件建立矮塔斜拉桥索鞍区有限元模型，选取整体计算中最不利荷载进行静力分析，得到了桥塔索鞍区混凝土和索导管应力分布状况，分析索鞍处混凝土应力规律，对索鞍锚固区设计方案进行综合评价，并提出改进建议。

| Abstract: | According to the design and the global analysis of a low-pylon cable-stayed bridge,three-di-mensional finite element model is set up via the finite element analysis software,and the stressed per-formance of the straddle-type cable saddle is studied.In local analysis,the stress distribution of the concrete of cable saddle zone and cable tube are obtained under the most unfavorable loads which is ob-tained from global static analysis.The design scheme of cable-pylon anchorage zone is evaluated based on the analysis of the stress distribution of cable saddle,and several improvement opinions are put for-ward. |
