摘　　要：南水北调东线工程一期山东段主体已经建成,建设期布设的测量控制网级别较低,且在施工过程中测量基点破坏较为严重。为满足工程运行初期渠道及主要建筑物安全监测要求,在南水北调东线一期工程山东境内测设了全线统一的变形监测网。以该监测网鲁南段为例,采用GNSS方法与高等级几何水准测量方法获取数据,系统论述了建设变形监测网的观测方案、技术指标、数据处理以及平差精度分析等内容。结果表明:高等级、高精度变形监测网的建成,为工程运行管理、变形监测提供了统一的控制基准,采用GNSS方法建设变形监测网,在作业精度、工作效率,监测连续性、实时性、受外界干扰小等方面体现出很大的优越性。南水北调东线一期工程山东段变形监测网的测设技术可为类似大型输水工程变形监测项目提供参考。The main body of Shandong section of the first phase of the East Route of South to North Water Diversion Project has been completed.The surveying control network laid out in the construction period was of a low level,and the measurement datum point was seriously damaged during the construction process.In order to meet the safety monitoring requirements of channels and main buildings in the initial stage of the project,a unified deformation monitoring network for the whole route has been set up in Shandong Province of the first phase of the East Route of South to North Water Diversion Project.Taking the southern Shandong section of the monitoring network as an example,GNSS method and high Leveling Surveying method are used to obtain data,and the observation scheme,technical indices,data processing and adjustment accuracy analysis of the construction of deformation monitoring network are systematically discussed.The results show that the construction of high-level and high-precision deformation monitoring network provides a unified control benchmark for engineering operation management and deformation monitoring,and the construction of deformation monitoring network by GNSS method shows great advantages in terms of operation accuracy,work efficiency,monitoring continuity,real-time and less external interference.The measurement technology of deformation monitoring network in Shandong section of the first phase of East Route of South to North Water Diversion Project can provide reference for deformation monitoring projects of similar large-scale water diversion projects.
