上承式钢管砼拱转体桥施工监测监控

Monitoring of Deck-type Steel Pipe Concrete Arch Swivel Bridge Construction

转体桥具有安全、可靠及整体性好等特点,适用于大跨境深沟、场地狭窄、地势陡峭等地形比较特殊的地形,从而解决由于地形构造的特殊性施工受到局限的问题。目前转体桥施工逐渐在我国公路、铁路上都得到推广。文章结合施工实践,就转体桥监测监控施工技术要点谈了一些体会。

Swivel bridge is characteristic in high safety, reliability and integrity, etc. and is suitable for special landforms such as large-span gorge, narrow site and steep area, etc., and it may solve the problem that construction is limited by special landforms. Swivel bridge is more and more popular in highway and railway construction in China. In combination with his construction practices, the author introduces some experiences in monitoring technologies in swivel bridge construction.
