Abstract
Located on Lanzhou-Chongqing Railway which serves as a 200 km/h mixed passenger and freight railway with double tracks, the 96m through-type arch bridge in the form of concrete-filled steel tube was designed so as to cross above the Chankou-Liugouhe Expressway. In view of the requirements on bridge of a mixed passenger and freight railway, this thesis introduced briefly the structure design and construction method of 96 m through-type arch bridge with concrete-filled steel tube. Meanwhile, by using two-dimensional and spatial calculation models respectively, the bridge was put into analysis in several aspects, including the static calculation, local stresses at the arch springing, natural vibration characteristic and spatial stability. The analysis result show that the design of this bridge is reasonable, and all the values of the design and calculation can meet the requirements stipulated in relevant codes.关键词
