90m+200m+90m连续刚构钢管拱桥施工关键技术研究

Study on Key Construction Technology of 90 m+200 m+90 m Continuous Rigid-frame Steel Tube Arch Bridge

摘要:

连续梁钢管拱桥作为我国的主要桥梁结构，具有施工便捷、安全、可靠，施工成本造价低等多种优点，被广泛应用于桥梁建设中。以府河特大桥90 m+200 m+90 m连续刚构钢管拱桥施工为例，对大跨度连续刚构钢管拱桥施工技术进行了详细的阐述分析,可供类似工程借鉴参考。

Abstract:

The continuous beam steel tube arch bridge is the main bridge structure in China, has many advantages of convenient, safe and reliable construction, and low construction cost, and is widely used in the bridge construction. Taking the construction of 90 m+200 m+90 m continuous rigid-frame steel tube arch bridge of Fuhe River Bridge as an example, the construction technologies of long-span continuous rigid-frame steel tube arch bridge are expounded and analyzed in detail, which can be referred for the similar projects.
