摘要
文章以G94珠三角环线高速跨线曲线钢箱梁桥的顶推施工为研究对象,针对其复杂的施工条件和特殊的桥跨组合,提出了平台组装、步履式多点连续顶推的施工方案.通过对顶推工艺的深入分析和精细控制,确保了施工的安全高效.研究成果可为类似桥梁工程施工提供重要的技术参考.
Abstract
This paper takes the incremental launching con-struction of G94 Pearl River Delta ring expressway cross-line curved steel box girder bridge as the research object,and puts forward the construction scheme of platform assembly and walking multi-point continuous incremental launching in view of its complicated construction condi-tions and special bridge-span combination.Through in-depth analysis and fine control of the incremental launch-ing process,the safety and efficiency of the construction are ensured.The research results can provide important technical references for the construction of similar bridge engineering.
