Static Analysis And Seismic Research Of Prestressed Concrete Continuous Box-girder Bridge

South-to-North Water Diversion Project is a challenging infrastructure project,which is the largest water diversion project all of over the world by far, and theseismic precautionary intensity of many segments is8degrees. The Xing Feng XianBridge is a prestressed concrete continuous box-girder bridge, which is one of thetypical cross channel bridge in South-to-North Water Diversion Project. Besides staticanalysis and seismic research, this paper carries out researches of the following twoaspects.Static aspects, the researches of the effect of side-web slope were concentratedon cable-stayed bridge or continuous box-girder bridge with equal sections, and thecontinuous box-girder with changed sections was always designed as verticalside-webs to simplify the computation and drawing works. This paper designs aprestressed concrete continuous box-girder bridge with changed sections and slantside-webs. The numerical analyses are carried out to discuss the effect of side-webslope on the loading properties of this bridge.Seismic aspects, taking the Xing Feng Xian bridge for example and choosingfive different pier height, this paper analyzes the effect of numerical factors byresponse spectrum annlysis method.
