珠江口水域的海底管道不仅受海洋水文环境和海床运动变化的影响,还因频繁水上水下人类活动使失效风险大大增加。文章针对珠江口水域管道面临外部风险进行分析,并提出防控措施。 Submarine pipelines in the Pearl River Estuary are not only affected by changes in the marine hydrological environment and seabed movement, but also greatly increase the risk of failure due to frequent underwater and underwater human activities. The paper analyzes the external risks facing the Pearl River Estuary pipelines and puts forward prevention and control measures.
