The Linked Early Warning Model of Soil Landslide Monitoring and Its Application
Under the current warning mode of landslide monitoring and warning information system,there are many false alarms in landslide warning work.Therefore,a"linkage early warning model"is proposed for landslide monitoring and early warning.The"linkage early warning model"uses a large number of landslide deformation monitoring data and adopts comprehensive index method to build an early warning model of landslide deformation and slide,which can jointly judge the overall movement state of landslide and make early warning and forecast.The model makes a comprehensive judgment from three aspects:the type of landslide monitoring equipment,the slope area and the deformation state of the monitoring point.Firstly,different weights are given according to different monitoring equipment.Second,the corresponding weights are determined according to different positions of the landslide where the monitoring equipment is located.Third,the corresponding deformation scores are determined according to the monitoring points at different stages of landslide deformation and failure.Finally,the early warning scores of landslide slip are determined through comprehensive calculation.The application of this model to the monitoring and warning of gradual soil landslide can effectively reduce the false alarm phenomenon and improve the monitoring and warning efficiency.The model can be applied to the monitoring and warning of similar landslides.
