摘要
该论文依托实际工程介绍不影响河道泄洪的多跨连续混凝土拱桥架空支架施工,包括多跨连续混凝土拱桥施工支架的搭设、计算分析和预压以及拱圈线形控制、混凝土浇筑和支架拆除的质量安全控制方法,为类似工程的施工提供参考。
Based on practical engineering cases,support construction and control of multi-spanned continuous arched bridge are introduced,including support erection,calculation,analysis and preloading and control methods for quality safety of arch ring linear control,concrete placing and support removal.It offers some references for similar engineering.
