大跨度钢筋混凝土肋拱桥的拆除与控制技术

Technology of Demolition and Monitoring on Long-Span Reinforced Concrete Ribbed Arch Bridge

结合南京市铁心桥拆除工程实例,介绍大跨度钢筋混凝土肋拱桥拆除施工方法选择、拆桥原则以及各部分构件的具体拆除顺序、施工工艺等,并详细论述拆除过程方案制定阶段的要点。介绍大跨度钢筋混凝土肋拱桥拆除过程结构理论模型建立、拆桥过程理论计算分析、现场结构响应监测内容和方法等。为今后类似桥梁的拆除提供参考。

The thesis makes detailed description the scheme selection of the demolition of long-span reinforced concrete ribbed arch bridge, which are the determining of the demolition way, principle, sequence and so on, with the Tiexin Bridge as the example. Modeling, theoretical calculation and analysis, contents and methods of demolition monitoring are also introduced. It can offer reference to the demolition of the same structure.
