基于数字孪生的海底地质灾害监测预警技术研究
Research on Submarine Geohazard Monitoring and Early Warning Technology Based on Digital Twin
摘要
Abstract
Subsea geohazard monitoring and early warning is very important for the safety of marine en-gineering,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 oc-currence 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 mo-nitoring and early warning system in Chengdao sea area,build a seabed engineering and geological envi-ronment 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 re-gional geohazard risk prevention and control.关键词
