摘　　要：近年来,我国桥梁工程技术日异月新,在高速公路、市政工程跨江大桥及新建铁路桥梁工程建设中,大型深水群桩基础形式得到广泛应用。文章结合某高速公路特大桥梁工程钢围堰深水群桩施工实例,对采用钢围堰在深水群桩施工中的工序流程安排、施工质量控制以及在钻孔灌注桩施工中遇到异常地质条件时的难点及对策进行分析阐述,希望能为桥梁的质量控制及施工提供参考。In recent years,the bridge engineering technology is developing rapidly in China,and in the construction of expressway, municipal engineering cross-river bridge and new railway bridge project, the form of large-scale deep-water group pile foundation is widely used.In combination with construc- tion example of steel cofferdam deep-water group pile in an expressway extra-large bridge,this article analyzed and discussed the process flow arrangement and construction quality control in deep-water group pile construction by using the steel cofferdam as well as the difficulties and countermeasures under abnormal geological conditions encountered in the construction of bored pile, hoping to provide a reference for the quality control and construction of the bridge.
