The high-cut slopes in the resettlement areas of the Sanxia Reservoir area, Chongqing were formed during the relocation of millions of people from the Sanxia Reservoir area. More than 26 years ago, they are widely distributed in the towns and cities of the resettlement areas, protecting infrastructure and the safety of residents' homes. However, with the increasing service life of many protective structures, material degradation, and the frequent occurrence of extreme weather events, the safety risks of these high-cut slopes are growing daily. If deformation and collapse occur, it will severely impact the production and lives of residents, endangering their lives and property.

This project conducted on-site investigations and analyses at 61 high-cut slope monitoring points. Monitoring equipment including visual deformation meters, crack gauges, inclinometers, fixed inclinometers, submersible water level gauges, video surveillance, and early warning broadcasts were used to acquire real-time deformation and disaster-prone environment information of the high-cut slopes. By setting monitoring and early warning thresholds, automatic early warning and alarms were achieved, forming a comprehensive solution for real-time monitoring, early warning and forecasting, information management, and decision support. A total of 43 visual deformation monitoring instruments, 64 audible and visual alarms, 5 crack gauges, 36 inclinometers, 1 deep inclinometer, 2 submersible water level gauges, 40 video surveillance systems, and 89 Beidou GNSS integrated monitoring units were deployed.

By leveraging Beidou communication, cloud computing, and big data technologies, a real-time monitoring and early warning system has been established for high slopes. This system provides data support for assessing the stability of high slopes and predicting trends in disaster development. Additionally, it offers scientific references for slope engineering treatments.
