铁路大跨钢管混凝土拱桥支架法拼装技术

Assembly Technology of Large-span Steel Pipe Concrete Arch Bridge in Railway with Cradle Method

结合广深港客运专线水田中桥工程实例,介绍铁路工程大跨度钢管混凝土拱桥支架法先梁后拱的拼装方法,既降低了施工安全风险,又保证了工期和拼装质量,为狭窄通道内铁路施工跨路拱桥提供了一种新的例证。

Based on the study of Shuitianzhong through steel pipe concrete arch bridge within Guangzhou-Shenzhen-HongKong passenger dedicated line,this article introduces a beam-before-arch assembly technology for the large-span steel pipe concrete arch bridge in railway enginerring.The method is to decrease the construction safety risks,guarantee the duration and quality and provide a new case for railway cross-road arch bridge construction in narrow passage as well.
