摘　　要：海上潜堤在施工过程中需对表层沉降进行监测,传统水准仪监测技术在潜堤常年覆盖海水的工况下无法正常实施,且无法满足对沉降观测数据的实时采集、存储、分析,因此,采用GNSS进行自动化监测便具有重要的实用意义。本文主要结合舟山某海上潜堤工程施工监测的实例,介绍了潜堤GNSS沉降观测墩的设计、安装、使用过程,并通过对施工监测数据的分析和及时反馈,实现了对施工沉降数据进行实时分析,同时对潜堤GNSS沉降观测墩进行了效益评价。The surface settlement of offshore submerged dike needs to be monitored during the construction.The traditional level gauge monitoring technology cannot be applied under the condition that the submerged dike is covered with seawater all year round,and the above instrument cannot support real-time gathering,storage and analysis of settlement data.Therefore,GNSS automated monitoring has considerably practical significance.The monitoring result of the construction of an offshore submerged dike in Zhoushan was studied,which showed the design,installation and use of GNSS settlement observation pier.In addition,the real-time analysis of construction settlement data could be realized through the analysis and timely feedback based on the construction monitoring data.The benefit evaluation was also made for GNSS settlement observation pier of the submerged dike.
