三峡工程规模宏大，建筑物种类繁多。安全监测是保证大坝安全运行、提高设计水平、改进施工方法的重要措施。三峡工程安全监测系统由资料量测及自动采集、巡视检查、资料管理及分析处理系统３部分组成。监测项目主要有变形监测、应力应变监测、渗压渗流监测、水力学原型观测、动力监测、水文泥沙观测、库首区地壳变形监测等，并由各量测子系统组成资料量测及采集系统。各监测项目将考虑各建筑物特点及地质情况，选定关键、重要、一般监测断、截面进行监测，并与监测网及库区地壳形变统筹布置。另外，为使三峡工程安全监测系统及时起到安全监控作用，对影响工程安全的重要监测断面（部位）将从施工期起逐步实行自动化监测。
The Three Gorges Project is huge in scale with a wide variety of buildings. Safety monitoring is an important measure to ensure the safe operation of the dam, improve the design level and improve the construction method. Three Gorges Project safety monitoring system consists of data measurement and automatic acquisition, inspection, data management and analysis and processing system composed of three parts. The main monitoring items are deformation monitoring, stress and strain monitoring, seepage pressure and seepage monitoring, hydrological prototype observation, dynamic monitoring, hydrological and sediment observation, crustal deformation monitoring in the reservoir area, etc., and the data measurement and collection system. Each monitoring project will take into account the characteristics and geological conditions of each building, and will select the key, important, general monitoring and monitoring sections, and coordinate with the monitoring network and the crustal deformation in the reservoir area. In addition, to enable the Three Gorges Project safety monitoring system to play a safety monitoring role in time, the important monitoring sections (parts) that affect the safety of the project will be gradually implemented automatic monitoring from the construction period.
