大型管节浮运关键技术分析

摘要

Taking the immersed tube tunnel project of Hong Kong-Zhuhai-Macao bridge as example , the long distance sea transportation method for large tunnel elements was presented , and the key technologies in the floating transport plan were ana-lyzed, such as the determination of resistance, time window and tug formation, etc.The final transportation plan was introduced .%以港珠澳大桥岛隧工程为例，介绍大型管节海上长距离浮运的方法，分析浮运方案设计的关键技术，探讨浮运阻力确定、时间窗口确定以及拖轮编队等问题，并确定最终方案。
