摘要

本文以某项目特大桥为背景,介绍了大跨度六线简支钢箱叠拱桥步履式顶推施工工艺.通过对悬拼法和顶推法对比,确定采用"旁位拼装、先横移、再纵向顶推"的施工方案.分析了六线简支钢箱叠拱桥的结构特点和技术难点,为后续研究提供了支撑.

Abstract

This article takes a large bridge project as the background and introduces the walking top push construction technology of a large span six track simply supported steel box stacked arch bridge.By comparing the hanging assembly method and the pushing method,the construction plan of"side assembly,first horizontal movement,and then vertical pushing"is determined.Analyzed the structural characteristics and technical difficulties of the six line simply supported steel box stacked arch bridge,providing a foundation for subsequent research.
