Method and Application of Geological Hazard Early Warning Based on Explicit Statistical Principle

On the basis of the second generation explicit statistical early warning model, based on the geological conditions and rainfall conditions of Zhongshan, a statistical early warning model for the area is constructed. On this basis, the zoning map of geological hazard is superimposed. At the same time, the plain area with elevation less than 10 meters is directly judged as no risk in the calculation process, so that it can reduce the amount of calculation and realize the more precise geological hazard warning in the study area. Compared with the early warning method of single point installation monitoring equipment in Zhongshan, the research area is divided into some small regions according to different terrain and geomorphology, and then the early warning formula of each region is derived. Finally, the early warning map of geological hazards is obtained by combining different regional formulas and geological hazard prone zoning maps. The experiment shows that the regional early warning method can be more accurate in positioning than the previous method, and the levels of early warning become more intuitive.
