SOUTH Geological Hazard Online Safety Monitoring System integrates dozens of major sensors such as deep displacement sensors, tilt sensors, crack sensors, earth pressure sensors, osmotic pressure sensors, and weather sensors. It also combines Beidou multi-satellite monitoring receivers, measuring robots, etc., which is widely used for geological disaster safety monitoring and structural health monitoring of reservoirs, dams, bridges and tunnels, and skyscrapers.
The main monitoring contents currently include:
Surface displacement monitoring: that is, the three-dimensional displacement (X, Y, Z), displacement direction and displacement rate of the deformed place (landslide, collapse);
Deep displacement monitoring: mainly to observe the overall displacement changes of rock and soil mass and the influence of its foundation;
Relative displacement monitoring: mainly monitoring of surface cracks;
Groundwater monitoring：analyzing the stability of landslides and collapses through dynamic changes in groundwater levels and water temperatures;
Rainfall monitoring: surface precipitation is the main source of groundwater recharge, and it has erosion effect on rock and soil;
Monitoring of soil: changes in internal stress, temperature and humidity of rock and soil may bring changes in stability of landslide and collapse;
Monitoring of pore water pressure: which has a significant impact on the internal stress of rock and soil;
Video surveillance: an important auxiliary means to grasp the situation on the spot and formulate emergency measures.
Monitoring and forecasting the causes, deformation, damage modes, directions, scales, times, and disaster conditions of various disaster-causing factors through a variety of information technology, and timely grasping various safety technical indicators and operating conditions of the monitoring area to provide the high-precision data for effective decision-making and governance.
1. Construction Project of Geological Hazard Monitoring and Early Warning System for State Grid Hubei Transmission Line
- Iron tower monitoring demonstration project in the plain area of the Yangtze River
Due to the complex geological conditions, abundant rainfall and the impact of human engineering activities, many types of geological disasters have occurred in Hubei Province, and they are widely distributed, frequent and serious. Based on comprehensive factors such as the danger degree of the power station's geological hazards, 4G signals, satellite signals, electromagnetic interference, and the geographic location of the monitoring stations and reference stations, the project finally determined the construction of 15 monitoring stations and 10 reference stations.
