| 摘 要： | 全面考虑结构的材料非线性和几何非线性，通过对一座跨径160m混凝土自锚式悬索桥进行全过程非线性分析，得到了结构的极限承载力。同时研究了材料非线性、加栽方式、约束条件对结构极限承载力的影响。结果表明，混凝土自锚式悬索桥的弹塑性极限承载力远小于弹性极限承载力，中跨加载情况的极限承载力与全桥加载情况相差不大，但主缆锚固端主梁的约束情况对结构的极限承载力影响较大。

| Abstract: | Based on nonlinear full-range analysis considering both geometrical and material nonlinearity,ultimate load-carrying capacity of a self-anchored concrete suspension bridge of 160 m in span is calculated.The research on effects of material nonlinearity,loading method,and restraint of bearing on ultimate loadcarrying capacity of the structure indicate that the elastic ultimate load-carrying capacity is much greater than elastic-plastic one,and the difference between loading in whole bridge and loading in mid-span is little,and the effect of restraint of bearing is much great. |
