摘 要: 结合苏通大桥科研专题与国际咨询审查成果,系统地就国内外研究中对大跨度斜拉桥静力稳定分析中所采用的加载方式、判定准则及其结论上的异同等关键问题进行了综合比较和分析研究,并指出一些亟待进一步探讨的问题. Based on some special study results and international review reports in the preliminary design of Su-Tong cable-stayed bridge, which is at present the largest cable-stayed bridge in the world with a main span of 1 018 m, a detailed comparison study on global static stability under some critical load cases is presented, including how to determine the variable instability loads, fundamental instability rules and some comments which mostly may be regarded as the current research subjects in this field.
