摘要
针对铁路连续刚构、一次性整体现浇实体梁板自重大的主要特点,通过对挑梁、钢管桩配军用梁支架体系的设计和验算,以工程实例阐述了现浇梁跨越复杂地形的施工方法。实践证明,该方法在施工中发挥了安全、可靠、高效的重要作用,取得了良好的社会效益和经济效益。
Based on the main features of railway continuous rigid frame,one-time overall casting of the entity slab of cantilever beam,the construction method of cast-in-place grouting beam across complex terrain is elaborated with project cases in accordance with the design and checking calculation of cantilever beam and the support system of steel pipe with Bailey bridge.The practice shows that this method is safe,reliable and efficient and that good social and economic benefits can be gained.
