摘要
滑道梁是钢桁梁顶推施工中重要的临时结构,其质量直接关系到桥梁施工能否安全顺利的完成。本文以黄大铁路黄河特大桥钢桁梁成功顶推到位为背景,重点论述了滑道梁设计、计算、安装等过程的关键技术及要点,为同类工程施工提供了可借鉴经验。
The slide beam is the important temporary structure in pushing construction of steel truss girder, its quality is di- rectly related to the bridge construction whether it can be completed safely and smoothly. Based on the successful pushing of steel truss girder in Yellow River Bridge of South Huanghua-Dajiawa Railway, this paper emphasized on the key technologies and main points in the process of slide beam design, calculation and installation, which could provide the referential experience for the construction of similar projects.
