Abstract

The Lane L8 of main-bridge of Xianyue Flyover across over Success Avenue is a reconstruction project with span of 39m+50m+39m. The circular-curved steel box girder has a uniform cross section with a multi-chamber single box. The characteristics of drag-type incremental launching and segment division of steel box girder were first introduced. In view of the characteristics such as curve shape, multiple segments and road complexity, and by comprehensively analyzing site condition, transportation condition and anti-overturning stability, the multipoint unidirectional twice-launching method was adopted herein, and its construction process was introduced. The technical problem such as disengagement of the steel girder from incremental launching platform in the course of launching was solved by jacking and real-time monitoring. The construction schedule was sped up, and meanwhile, safety was guaranteed. This study can provide valuable references for similar engineering projects.
