铁路桥梁基础及下部结构施工技术探讨铁路桥梁基础及下部结构施工技术探讨 摘要：作为生产运输的重要基础设施，铁路桥梁获得了很大的进展，随着机车轴重的增加和速动的提高，对桥梁铁路提出了更高的设计要求。要想提高铁路桥梁施工的质量，需要采纳先进的技术对施工进行指导。本文共分两部分，第一部分通过挖孔桩和钻孔灌注桩详细介绍了桥梁桩基础施工的技术要点，第二部分从桥梁的盖梁、墩台和承台施工三方面详细探讨了铁路桥梁下部结构施工的技术要点。 关键词：铁路桥梁；桩基础；钻孔灌注桩；混凝土；承台 Abstract: as an important infrastructure, production and transportation of railway Bridges obtained great development, with the increase of the locomotive axle load and quick rise, to the design of Bridges of railway put forward higher requirements. If you want to improve the quality of the construction of railway Bridges and to adopt advanced technology for guidance of construction. This article is divided into two parts, the first part through the excavated belled piles and bored piles are introduced in detail the main technical points of the bridge pile foundation construction, the second part from the bridge of capping beam, pier and cap construction three aspects discussed in detail the main technical points of the infrastructure construction of railway Bridges.
