摘　　要：本文创新了基于海底实时监测数据驱动的海底工程地质环境数字孪生模型,建立了一套埕岛油田地质灾害监测预警系统,构建了海底工程地质环境数据库,实现了对海底监测数据的远程实时可视化更新及交互控制。该系统应用于埕岛海底地质灾害监测,在持续运行的40天监测周期内,累计警报了2次强海底侵蚀灾害,提示了4次高浊度事件,真实反映了研究区海底侵蚀变化。本文首次尝试将数字孪生技术融合到海底地质灾害的监测预警中,为区域地质灾害防控提供了一种新的技术参考。Subsea geohazard monitoring and early warning is very important for the safety of marine engineering,but the current subsea geohazard database only stays in the compilation of historical data,which makes it difficult to grasp the changes of marine environment in real time and cannot warn the occurrence of disasters in time.A digital twin model of seabed engineering and geological environment driven by real-time seabed monitoring data has been innovated to establish a set of seabed geohazard monitoring and early warning system in Chengdao sea area,build a seabed engineering and geological environment database,and realise remote real-time visualisation update and interactive control of seabed monitoring data.The system was applied to the seabed geohazard monitoring in Chengdao sea area,and during the 40-day monitoring cycle of continuous operation,two strong seabed erosion hazards were warned and four high turbidity events were suggested,which proved that the system operated stably in the early warning of seabed erosion and siltation hazards.The first attempt to integrate digital twin technology into the monitoring and early warning of submarine geohazards provides a new idea for regional geohazard risk prevention and control.
