飞燕式拱桥半幅主拱圈现浇支架稳定性控制技术

Stability Control Technology of Cast-in-place Scaffold for Half-frame Main Arch Ring of Fly-bird Type Arch Bridge

地基处理对现浇支架的稳定性至关重要。结合沪杭城际高速铁路跨沪杭高速公路转体拱桥施工实例,介绍了软弱地质条件下地基处理及现浇施工支架结构设计,供同类工程参考。

Foundation treatment is very important to the stability of cast-in-place scaffold.Based on the construction example of swing arch bridge of Shanghai-Hangzhou High-speed Inter-city Railway overcrossing the Shanghai-Hangzhou expressway,this article introduces the treatment of soft soil foundation and design of cast-in-site scaffold structure for the reference of similar projects.
