小半径缓和曲线钢板组合梁整体顶推技术

Overall Thrust Technology of Steel Plate Composite Beam With Small Radius and Gentle Curve

近年来,在山区桥梁设计中越来越多的应用了钢板组合梁。因此,以某工程为例,其采用钢板组合梁,桥梁平面位于小半径圆曲线及缓和曲线上,场地受限,仅能采用顶推工艺,因此总结了小半径缓和曲线钢板组合梁整体顶推技术要点,从而为类似工程提供一定借鉴。

In recent years,more and more steel plate composite beams have been applied in the design of mountain bridges.Therefore,taking a project as an example,it adopts a steel plate composite beam. The bridge plane is located on a small radius circular curve and a mitigation curve. The site is limited.Only the top pushing process can be used to analyze a project,therefore,the main thrusting technical points of the small radius tempered curve steel plate composite beam are summarized,which provides a reference for similar projects.
