特殊条件下跨河特大桥施工方法探讨

Discussion on Construction Method of Cross-river Extra Large Bridge Under Special Conditions

本文基于我国现有铁路桥梁施工面临的地形地质条件和施工环境等特殊条件,以某铁路跨河特大桥施工为例,对其施工面临的重点难点进行分析,并基于此提出针对性的安全施工方案。笔者认为特殊条件下跨河特大桥的施工重点在于提出有效的施工方案,基于方案进行科学的组织生产和安全管理,并做好突发事件的应急处置。

Based on the topographic and geological conditions,construction environment and other special conditions faced by the existing railway bridge construction in China,this paper takes the construction of a railway cross-river extra large bridge as an example,analyzes the key points and difficult points faced by its construction,and puts forward a targeted safety construction scheme based on this.The author believes that the key point of the construction of the cross-river extra large bridge under special conditions is to put forward an effective construction plan,organize production and safety management scientifically based on the plan,and handle emergencies well.
