摘要
采用支架施工的大跨钢筋砼(RC)拱桥施工中的关键技术问题主要包括主拱圈高度与浇筑的时间确定、主拱圈分段长度与浇筑程序的确定、主拱圈落架方案的拟定.通过介绍许沟大桥在上述三个方面的工程实践与应用,为该类桥梁的建设提供借鉴与参考.
The key technical problems in construction of long span reinforced concrete arch bridge with scaffold include: layer's height of main arch, time of pouring concrete , subsection's length of main arch, procedures of pouring and decentering of main arch etc. This paper provides some references for constructing bridges of this type by a case study of Xugou Bridge.
