[Objective] The automatic monitoring system of soil-saving dam was designed to realize the real-time transmission and early warning of monitoring data, and improve the safety management ability for soil-saving dams.[Methods] Five typical dams were selected as the pilot for the design, construction, installation and trial operation of the automatic safety monitoring system of soil-saving dams. A safety prediction model for soil-saving dam was established.[Results] The system realized the automatic collection of monitoring data for rainfall, water level, seepage pressure, deformation, displacement, stress, and video of soil-saving dam, realized the prediction and early warning of potential safety hazards, and improved the safety monitoring ability of soil-saving dam.[Conclusion] The operation of the system is helpful to enhance the safety management of the warping dam system in the whole He'nan Province, and to provide a new information management mode for the soil-saving dam safety operation in the Loess Plateau in flood season.
