Abstract
The Liujiaxia Yellow River Bridge is one of the key projects of newly built railway from Lanzhou to Hezuo. It is located in high seismic intensity region. The main bridge is (100+180+100)m of continuous rigid frame to cross the Yellow River and highway interchange. The height of the pier is 105m, so the bridge has the typical characteristics of high pier and long-span, which add more difficulties in bridge design and construction control. This paper introduces the girder of main bridge and main pier size and conducts static calculation according to the construction phase. The Dynamic calculation includes the determination of earthquake fortification standard and earthquake input, determination of dynamic calculation model and the analysis of dynamic behavior of structure, the determination of anti-seismic performance target and verification principle. Fibrous unit division is made and seismic response and response spectrum analysis is carried out. The results show that the bridge meets relevant requirements of the code.关键词
