摘要
重庆鹅公岩轨道大桥位于既有鹅公岩大桥上游70 m,主桥采用钢箱梁自锚式悬索桥结构。结合大桥专题科研成果,就三家研究单位在研究中对超大跨径自锚式悬索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综合比较和分析研究,并对后续工作做出展望。
Egongyan Track Bridge in Chongqing City is located at the upper stream 70 m of the existing Egongyan Bridge.Its main bridge is a steel box beam self-anchored suspension bridge.Combined with the special scientific research achievements of the bridge,the loading methods and decision criteria used in the analysis on the static stability of overlong-span self-anchored suspension bridge by three institutes,and the key problems of the similarities and differences of the conclusions are comprehensively compared,analyzed and studied.The follow-up work is prospected.
