Abstract

Abstract

Seismic design of bridges across active fault zones is a complex and systematic problem. Yingpan Bridge was taken as a research subject, which crossed the Longshu-Houzipo breakage of Ludian earthquake fault zone in Yunnan Province. A comprehensive study of domestic and international codes and research results was investigated based on the analysis of the seismic structural characteristics of the bridge location and bridge the requirements for seismic resistance. The seismic design of the bridge in the high seismic intensity zone was carried out with the consideration of the influence of the fracture dislocations generated by the active fault zone on the structure. According to the design concept and principle of "multiple lines of defense and graded energy consumption", design strategies and concrete anti-seismic measures of Yingpan Bridge were put forward from aspects of seismic conceptual design of bridge,seismic isolation design and anti-falling beam system, which could providea reference for the seismic design of samilar structures.
