九龙江特大桥深水基础钢套箱围堰施工技术

摘要

By taking the deep foundation construction of Jiulongjiang double-line super-large Bridge as the example,the paper introduces the construction technique of the steel boxed cofferdam in deep water foundation of the bridge＇s main pier,that is,＂the pile construction prior to the cofferdam construction＂,and illustrates the feasibility of the application of the steel boxed cofferdam in deep water foundation.%结合九龙江双线铁路特大桥深水基础施工实例,介绍了大桥主墩＂先桩后堰＂的深水基础钢套箱围堰施工技术,并通过实践证明了钢套箱围堰施工技术在深水基础中应用的可行性。
