【Abstract】 Post-disaster reconstruction design of four Yuzixi bridges in Yingxiu town is introduced in this paper. Basing on the research of the bridges in the disaster zone and the design practice of these bridges,some new concepts of the seismic design in the similar disaster zone is summarized.According to the very serious secondary damage in earthquake, simply supported structure of standard span is considered to be one of the most suitable bridge-type.In Yuzixi municipal bridge design,designers pay a lot of attention to the seismic design,landscape and details of design,which cao provide a reference for other seismic projects.更多还原
