InactiveCN103424099AImprove acquisitionAvoid missingMeasurement devicesAlarmsEarly warning systemSlope monitoring
A slope monitoring and early warning system based on deformation data comprises a plurality of surface displacement devices and a communication base station. The surface displacement devices send collected data information to the communication base station, and data interaction is carried out between the communication base station and a far-end monitoring center. According to a slope monitoring and early warning method based on the deformation data, a slope stability computational formula is deduced according to measured point displacement values and angle deviation values through analysis on a slope deformation instability mechanism based on theories of rock and soil mechanics. Dangerousness states on a slope are judged according to slope stability coefficient indexes, and therefore dangerousness classification on the slope can have fixed indexes and standards. The slope monitoring and early warning method based on the deformation data is different from the existing displacement-time method that different slopes have different early warning displacement values.
