摘要
钢筋混凝土拱桥悬臂施工分为悬臂拼装法和悬臂浇筑法两大类。悬臂浇筑法主要采用挂篮悬臂浇筑施工,根据国内外目前的工艺技术又可以分为采用塔架斜拉扣挂法和悬臂桁架浇筑法。以马蹄河特大桥为背景,介绍大跨度塔架斜拉扣挂法悬臂浇筑拱桥的关键施工技术。实践表明,斜拉扣挂法悬臂浇筑拱桥具有结构整体性好、造价相对低、后期维护费用低、工期短的优势。
Cantilever construction of reinforced concrete arch bridge can be devided into cantilever assembling and cantilever casting. Cradle cantilever casting was mainly adopted in cantilever casting which includes stayed knotting method and cantilever truss casting method. Based on engineering practice of Matihe Bridge, this paper introduced the key technologies of stayed knotting method of large-span reinforced concrete arch bridge. Engineering practice shows that it has the advantsges of good integrity, low cost and short construction period.
