大直径钢圆筒振动下沉工艺及设备的开发与应用

摘要

Taking the island and tunnel project of the Hongkong-Zhuhai-Macao Bridge as an example, we discussed the equipment selection, construction process and implementation effect for vibration sinking technology of large diameter steel cylinder. The technology of rapidly completing island by large diameter steel cylinder retaining structure provides security and stability retaining structure for the dry construction in the island.%以港珠澳大桥主体工程岛隧工程为例，全面论述了大直径钢圆筒振沉的设备选型、施工工艺及工程实施效果。大直径钢圆筒围护结构快速成岛技术，为岛内干施工提供了安全、稳定的止水围护结构。
