Study and Design of Pre-Stressed Concrete Trough Girder of Shijiazhuang-Ji'nan Dedicated Passenger Railway Line
摘要
Abstract
In order to reduce the height of embankment at both ends of the line near the railway station, to reduce project investment and, at the same time, to meet the requirement to cross flood control and interchange road, through bridge of trough girder structure with lower building structure can be used. With reference to the new project of Shijiazhuang to Ji'nan dedicated passenger railway line across the beam structure of YuWang Road, structure analysis and design optimization are conducted by finite element software. The double track groove design analysis of beam structure, spatial structure calculation of the trough beam and spatial analysis and dynamic characteristics of vehicle track bridge coupling dynamic are presented. The channel beam combined effect of bending shear torsion and the box girder section edge spatial deformation are considered comprehensively in current applications. Trough continuous beam is less used in high speed railway engineering due to the lack of specific experience and theoretical formula. The solution of such technical problem provides an important reference for similar bridge design.关键词
