CHCNAV Landslide Warning System

Project Background

CHCNAV automated monitoring system for geological hazards provides scientists, engineers, and disaster monitors with real-time, invaluable information on buildings or natural disaster early warning. This system frees the operators from carrying on the time-consuming work such as post-processing and result analyzing. Meanwhile, it displays the deformation quantity in the real-time, which significantly prolongs the early warning duration and reduces the loss of life and property. 

Technical Advantages

 The early warning system of Zhouqu landslide was built on the landslide body of Zhouqu County Suoertou village in Gansu Province, China. GPS surface displacement, internal inclinometer, crack meter, seepage pressure meter, TDR and other sensors in one integrated monitoring system, can conduct a real-time collection of data from the sensors, transmission to the monitoring and warning platform, and according to the set alarm coefficients, alarming in real-time. 

Solution

Started from October 2011 and lasted for nearly a year, the project department overcame a series of difficulties and completed the construction and installation of the Zhouqu landslide project monitoring facility in September 2012. Combined with six kinds of monitoring methods, the project includes the establishments of :

-14 landslide monitoring stations, 

-41 GPS surface displacement monitoring stations (including two reference stations), 

-9 inclinometer and osmotic pressure internal monitoring stations, 

-17 crack monitoring stations, 

-2 water Weir Water monitoring stations, 

-1 TDR deep monitoring stations, 

-and 1 set of section monitoring stations at Shuileigou.
