| Abstract: | 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. |
